An international non-profit encompassing both amateur and professional astronomers, the American Association of Variable Star Observers (AAVSO) provides assistance with stellar activity monitoring, statistical analysis, and many more key components of astronomical research.
Used to determine the quality of your image, the Full Width Half Maximum (FWHM) process is used to determine the quality of images and is of particular importance in photometric and exoplanet research work. BRIEF primarily uses the OSS Pipeline to account for the FWHM process.
This lesson shows how to identify a target star in a specific image using the WCS coordinates provided by either Astrometry.net or SAOImageDS9.
The main sequence is defined by the HR diagram movement of a star fusing hydrogen into helium within its core, and understanding the relationship between the luminosity, temperature, radius and mass of stars on the main sequence allows us to derive useful information from a star's location on it.
AstroImageJ (AIJ) is the industry standard for measuring exoplanet transits as well as accurately measuring double stars, and has quickly become a core component of the astronomical sciences. This video is a guide and reference for anyone using AIJ for double stars measurements.
