14627 Emilkowalski
14627 Emilkowalski (Minor planet provisional designation, ''prov. designation'': ) is a stony asteroid from the central region of the asteroid belt, approximately in diameter. It was discovered on 7 November 1998, by American astronomer Richard Kowalski at the Quail Hollow Observatory () in Zephyrhills, Florida, United States. The asteroid is the namesake of the recently formed Emilkowalski family of asteroids. It was named after Emil Kowalski, mentor of the discoverer. Orbit and classification ''Emilkowalski'' orbits the Sun in the Kirkwood gap, central main-belt at a distance of 2.2–3.0 Astronomical unit, AU once every 4 years and 2 months (1,531 days). Its orbit has an orbital eccentricity, eccentricity of 0.15 and an orbital inclination, inclination of 18Degree (angle), ° with respect to the ecliptic. The first unused observation at Palomar Observatory (Digitized Sky Survey, DSS) dates back to 1953. The first used precovery was taken at Siding Spring Observatory i ...

Lightcurve
In astronomy, a light curve is a graph of light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y axis and with time on the x axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid variables, other periodic variables, and transiting extrasolar planets, or aperiodic, like the light curve of a nova, a cataclysmic variable star, a supernova or a microlensing event or binary as observed during occultation events. The study of the light curve, together with other observations, can yield considerable information about the physical process that produces it or constrain the physical theories about it. Variable stars Graphs of the apparent magnitude of a variable star over time are commonly used to visualise and analyse their behaviour. Although the categorisation of variable star types is increasingly done from their spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
