Astronomical Institute Of Slovak Academy Of Sciences
The Astronomical Institute of Slovak Academy of Sciences was founded in 1953, when the state observatory on Skalnaté Pleso (founded in 1943 by Dr. Bečvář) got a status of astronomical institute and became one of the founding institutes of the newly born Slovakian Academy of Sciences. In memories of past and current employees, the institute and the observatory on Skalnaté Pleso were always blended in one and therefore one could consider for the year of the institute foundation already the 1943. Currently, it has its headquarters at Tatranská Lomnica. Field of research and organization of the institute The institute focuses its research on the Sun, interplanetary matter (comets, meteoroids, asteroids) and on astrophysical research of variable and chemically peculiar stars. It has about 65 permanent employees of which roughly 50 are active researchers. It is divided into 3 departments: Department of Solar Physics Interest in solar atmospheric activity led the department to ...

Star System
A star system or stellar system is a small number of stars that orbit each other, bound by gravity, gravitational attraction. It may sometimes be used to refer to a single star. A large group of stars bound by gravitation is generally called a ''star cluster'' or ''galaxy'', although, broadly speaking, they are also star systems. Star systems are not to be confused with planetary systems, which include planets and similar bodies (such as comets). Terminology A star system of two stars is known as a ''binary star'', ''binary star system'' or ''physical double star''. Systems with four or more components are rare, and are much less commonly found than those with 2 or 3. Multiple-star systems are called ''triple'', ''ternary'', or ''trinary'' if they contain three stars; ''quadruple'' or ''quaternary'' if they contain four stars; ''quintuple'' or ''quintenary'' with five stars; ''sextuple'' or ''sextenary'' with six stars; ''septuple'' or ''septenary'' with seven stars; and ' ...

Ľudmila Pajdušáková
Ľudmila Pajdušáková (29 June 1916 – 6 October 1979) was a Slovak astronomer. She specialized in solar astronomy, and also discovered a number of comets, including periodic comet 45P/Honda-Mrkos-Pajdušáková, and the non-periodic C/1946 K1 (Pajdušáková-Rotbart-Weber), C/1948 E1 (Pajdušáková-Mrkos), C/1951 C1 (Pajdušáková) and C/1953 X1 (Pajdušáková). She observed at Skalnaté Pleso Observatory and became its third director from 1958 to 1979. The asteroid 3636 Pajdušáková is named after her. She was married to Antonín Mrkos. In a 1951 "Comet Notes" article in ''Publications of the Astronomical Society of the Pacific'' [PASP 63 (1951) 209], Leland E. Cunningham in discussing comet C/1951 C1 refers to her as "Miss Pajdušáková (Mrs. Mrkos)", and there was an astronomy book published in 1956 by Ľudmila Mrkosová-Pajdušáková, as well as various scientific papers under this name from approximately 1952–1958. However, their respective biographies do not s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antonín Bečvář
Antonín Bečvář (; 10 June 1901 – 10 January 1965) was a Czechoslovak astronomer. Biography He was born and died in Stará Boleslav. Among his chief achievements is the foundation of the Skalnaté Pleso Observatory and the discovery of the comet C/1947 F2 (Bečvář) (also known by the designations 1947 III and 1947c). His lifelong illness led him to the High Tatras where he founded the observatory. Bečvář is particularly important for his star charts: he led the compilation of the ''Atlas Coeli Skalnate Pleso'' (1951), published by Sky Publishing Corporation as the '' Skalnate Pleso Atlas of the Heavens'', which was the state-of-the-art atlas of its kind until Wil Tirion's "Sky Atlas 2000.0" in 1981. A dozen star names in the atlas are of unknown origin, no connection to any language or previous source has been discovered despite an extensive search. He also compiled ''Atlas eclipticalis, 1950.0'' (1958), ''Atlas borealis 1950.0'' (1962), and ''Atlas australis 195 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectrometer
A spectrometer () is a scientific instrument used to separate and measure Spectrum, spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were History_of_spectroscopy, developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine Analytical_chemistry#Spectroscopy, chemical composition drove its advancement and continues to be one of its primary uses. Spectrometers are used in Astronomical spectroscopy, astronomy to analyze the chemical composition of Astronomical_spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coronograph
A coronagraph is a Telescope, telescopic attachment designed to block out the direct light from a star or other bright object so that nearby objects – which otherwise would be hidden in the object's bright Glare (vision), glare – can be resolved. Most coronagraphs are intended to view the solar corona, corona of the Sun, but a new class of conceptually similar instruments (called ''stellar coronagraphs'' to distinguish them from ''solar coronagraphs'') are being used to find extrasolar planets and circumstellar disks around nearby stars as well as host galaxies in quasars and other similar objects with active galactic nuclei (AGN). Invention The coronagraph was introduced in 1931 by the French astronomer Bernard Lyot; since then, coronagraphs have been used at many Solar observatory, solar observatories. Coronagraphs operating within Earth's atmosphere suffer from scattered light in the sky itself, due primarily to Rayleigh scattering of sunlight in the upper atmosphere ...

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. Overview In a CCD image sensor, pixels are represented by Doping (semiconductor), p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lomnický štít
Lomnický štít (, , , ) is one of the highest and most visited mountain peaks in the High Tatras mountains of Slovakia. Connected by cable car to Tatranská Lomnica, its summit is above sea level, making it the second highest peak in the High Tatras after Gerlachovský štít (2654 m). Local shoemaker and amateur miner Jakab Fábry stated he made an ascent around 1760–1790, but the first recorded ascent was made by the English traveler Robert Townson and guide on 16 August 1793. He measured the elevation of the peak to be 2633 m, a meter below the actual elevation. The first winter ascent was made in 1891. In the past, Lomnický štít was called as ''Vater'' (Father), ''Grossvater'' (Grandfather), ''Königsberg'' (King's Mountain), ''Królowa Tatr'' and ''Królowa Tatrzańska'' (Princess of the Tatra), ''Petra altissima kesmarkiensis'' and ''allerhöchster Kaisermärkerfels'' (Highest cliff of Kežmarok), ''höchste Kaisermärker Spitze'' (Highest peak of Kežmarok), ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysics, oceanography and volcanology are examples of disciplines for which observatories have been constructed. The term ''observatoire'' has been used in French since at least 1976 to denote any institution that compiles and presents data on a particular subject (such as public health observatory) or for a particular geographic area (European Audiovisual Observatory). Astronomical observatories Astronomical observatories are mainly divided into four categories: space observatory, space-based, airborne observatory, airborne, ground-based, and underground-based. Historically, ground-based observatories were as simple as containing a mural instrument (for measuring the angle between stars) or Stonehenge (which has some alignments on astronomical phenomena). Ground-based observatories Ground-based observatories, located on the surface of Earth, are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
