Stellar chromospheric activity of LAMOST sources
The dependence of stellar magnetic activity on stellar parameters is inspired by the chromospheric activity studies based on the large-scale spectroscopic surveys. The main... -
Activity indexes analysis
Stellar activity is the most relevant types of astrophysical noise that affect the discovery and characterization of extrasolar planets. On the other hand, the amplitude of... -
Flare cumulative frequencies of UV Ceti stars
In this study, as a result of the photometric observations continued on nine UV Ceti type stars, examining the parameters obtained from the models of distributions of the flare... -
Magnetic activity based on LAMOST and Kepler
Stellar magnetic activity is an interesting phenomenon in late-type stars. We use the medium-resolution spectroscopic observations of 406069 late-type stars from LAMOST to... -
Superflares in solar-type stars with TESS
Superflares on solar-type stars have been a rapidly developing field ever since the launch of Kepler. Over the years, there have been several studies investigating the... -
Coronal mass ejections on solar-like stars
Coronal mass ejections (CMEs) may have major importance for planetary and stellar evolution. Stellar CME parameters, such as mass and velocity, have yet not been determined... -
Spot modeling of V1298 Tau using SpotCCF tool
The intrinsic variability due to the magnetic activity of young active stars is one of the main challenges in detecting and characterising exoplanets. The stellar activity is...
