Characterisation of starspot structure and differential rotation of Kepler-411
Astronomy & AstrophysicsContext. Starspots and their movements on stellar surfaces enable the mechanisms of stellar magnetic activity to be investigated. Information on the spot distribution and differential rotation provide important constraints for the behaviour of stellar ...

Starspot Distribution and Flare Events in Two Young Low-mass Stars Using TESS Data
The Astrophysical JournalWide-field high-precision photometric observations such as the Transiting Exoplanet Survey Satellite (TESS) allowed the investigation of the stellar magnetic activity of cool stars. M dwarf starspots and stellar flares are the main indicators of magnetic

The discovery of starspots in cataclysmic variables
, 2016 We have developed a new method to detect starspots on the surface of the secondary star in cataclysmic variables. We demonstrate that it is a good method, by deducing the host star spectral type, the temperature and percentage coverage of spots, of two U

Further Study of Starspot Activity and Measurement of Differential Rotation for SZ Piscium
The Astrophysical JournalWe present a series of nine Doppler images of the magnetically active K component of the RS CVn-type binary SZ Piscium (SZ Psc), based on high-resolution spectroscopic data collected from 2014 to 2018.

Probing Starspot Dynamics on the Active M Dwarf TIC 272272592: A Multiyear TESS Study
The Astrophysical JournalWe present an analysis of temporal starspot evolution and its distribution on an active rapid rotator ( P _rot = 1.22 days), TIC 272272592, using high-precision time-series photometry from the Transiting Exoplanet Survey Satellite spanning over 3 yr. The

Computational starspot photometry of contact binary stars
, 2007 Starspots are not well understood for contact binary star systems. The following properties of spots were systematically investigated: temperature, radius, colatitude, and longitude. Spots were modeled on an AE Phe like contact binary system.

Starspot Temperature of CoRoT-2 from Multiwavelength Observations with SPARC4
The Astrophysical JournalMeasuring starspot temperatures is crucial for understanding stellar magnetic activity as it affects stellar brightness variations, influences exoplanet transit measurements, and provides constraints on the physical conditions and energy transport in ...
