Starspots on the active young solar-type star AH Lep
, 2010 Young solar-type stars inform us about the early evolution of objects that form a major component of the stellar population of our galaxy. Single active young solar-type stars close to the Sun’s mass also provide us with proxies for the Sun’s early ...

Study of stellar activity through transit mapping of starspots
, 2010 During the eclipse of a planet, spots and other features on the surface of the host star may be occulted. This will cause small variations in the light curve of the star.

Starspots: A Key to the Stellar Dynamo
, 2005 Magnetic activity similar to that of the Sun is observed on a variety of cool stars with external convection envelopes. Stellar rotation coupled with convective motions generate strong magnetic fields in the stellar interior and produce a multitude of ...

14. Irregularities In Young Stellar Models: Are Starspots To Blame?
, 2018 Starspots are dark areas on a star’s surface formed by intense magnetic fields that actively suppress the flow of energy, causing the area to become cooler and darker than its surroundings.

The Astrophysical Journal, 1974 Sizes of starspots on flare stars can be derived from the author's convection-cell hypothesis. The sizes are in fair agreement with those observed on YY Gem, CC Eri, and BY Dra by Bopp and Evans (1973). The hypothesis predicts that periodic brightness variations due to starspots are restricted to stars brighter than a critical absolute visual ...

Starspots and active regions on the chromospherically active binary MS Ser
, 2003 The quasisimultaneous electrophotometric, polarimetric and spectroscopic observations of the chromospherically active binary MS Ser are presented. The photometric variability of the star can be described completely by a zonal spottedness model.

Starspots Found on the Ellipsoidal Variable V350 Lacertae = HR 8575 [PDF]
, 1995 It has been a puzzle why this chromospherically active, strong-dynamo K2 IV-III star is not known to have the large starspots characteristic of other such stars. Published individual radial velocities, which had never been analyzed, are used to derive an

The discovery of starspots in cataclysmic variables
, 2001 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
