Stellar rotation and binaries in open clusters with Gaia DR3
Elena Pancino, Elisabetta Reggiani, Silvia Marinoni +14
Stellar rotation is a fundamental ingredient in shaping the evolution of stars and it can also be used to trace past stellar interactions. Yet, systematic studies of stellar rotati…
Colour-Based Disentangling of Mira Variables and Ultra-Cool Dwarfs
Aleksandra Avdeeva, Kefeng Tan, Santosh Joshi +4
Despite having different astronomical characteristics, the studies of mira variables and ultra-cool dwarfs frequently show similar red colors, which could cause leading to photomet…
New ultracool dwarf candidates from multi-epoch WISE data
Sergey Karpov, Oleg Malkov, Aleksandra Avdeeva
Thirty years after the discovery of brown dwarfs, the search for these objects continues, particularly in the vicinity of the Sun. Objects near the Sun are characterized by large p…
Fitting procedure for estimating interstellar extinction at high galactic latitudes
Aleksandra Avdeeva, Dana Kovaleva, Oleg Malkov +1
We determine the interstellar extinction in the selected high-latitude areas of the sky based on Gaia EDR3 astrometry and photometry and spectroscopic data from RAVE survey. We app…
