When compared to distributions of nearby OB stars the distribution of reddening of RSGs both in LMC and Galaxy is skewed significantly toward higher values. Thus RSGs show extra extinction due to circumstellar dust ...

New Double Stars from Asteroidal Occultations, 1971 - 2008
... The occultation is recorded as the sudden disappearance of the star, followed some seconds (or tens of seconds) later with a sudden reappearance of the star. For a small number of events, the occultation may involve: A partial drop in light, followed by a complete drop in light. The order of the lig ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
