Activity of Selected Solar Twins
M. M. Katsova, B. A. Nizamov, A. A. Shlyapnikov
We analyze various tracers of magnetic activity for 23 solar twins which are characterized by significant scatter of lithium abundance in their atmospheres. A level of coronal and…
Detection of Optical Flares on the Selected G-M Dwarfs from Long-term Photometric Series
N. I. Bondar', M. M. Katsova, A. A. Shlyapnikov
We have carried out a search for flares from the analysis of light curves for 12 active G, K, and M dwarfs. As sources of data we used ground-based observations in 2000-2020 from t…
The Transit Timing and Atmosphere of Hot Jupiter HAT-P-37b
Napaporn A-thano, Ing-Guey Jiang, Supachai Awiphan +13
The transit timing variation (TTV) and transmission spectroscopy analyses of the planet HAT-P-37b, which is a hot Jupiter orbiting an G-type star, were performed. Nine new transit…
Archives of CrAO spectral observations. Catalogues of objects and images
A. A. Shlyapnikov, M. A. Gorbunov, M. A. Gorbachev +1
The work described in this article is a continuation of the previously initiated research on archival spectral observations carried out in the Crimea. It covers a time interval of…
Flares activity of selected stars from GTSh10 catalog by CRTS data
M. A. Gorbachev, A. A Shlyapnikov
Based on the database of photometric observations of the CRTS project over an interval of more than 9 years, the activity of red dwarfs from the GTSh10 catalog was analyzed. The to…
A software for streaming processing of photometric observations
V. V. Moskvin, A. A. Shlyapnikov
Software products nova.astrometry.net, SExtractor and Aladin are shown to be used for searching for transient phenomena in series of photometric images. An algorithm for taking int…
