Spottedness vs Flare number: Are they related?
In order to check whether the spottedness on the stellar surface is related to the occurrence rate of flare, we plotted the distribution...
Variation of stellar spottedness with surface-temperature on active solar-type stars
The spottedness (S) vs. stellar effective temperature (T_eff) plot for F–M type stars taken from the catalog of McQuillan et al. (2014)....
Starspots: Observation of photosphere, chromosphere, vs. corona
From top to bottom the X-ray, UV, and optical folded light curves are shown. Each folded light curve is binned at bin-size 0.1. The...
Starspot evolution and flip-flop cycle from long-term photometry on a K-dwarf
Parameters of K-dwarf LO Peg derived from modelling have been shown. From top to bottom – (a) V-band light curve of LO Peg (open...
Starspot Evolution on stellar surface on a F-type star constructed from Kepler observations
The F-type star KIC 6791060 was observed for four years from 13 December 2009 to 13 December 2013 by the Kepler satellite. The Kepler...
F-type ultra-fast rotator KIC 6791060
The 3-minute presentation I have given at the first Belgo-Indian Network for Astronomy & Astrophysics (BINA) Workshop in ARIES, Nainital,...
