How do starspots influence the transit timing variations of exoplanets? Simulations of individual and consecutive transits

, 2015
Transit timing variations (TTVs) of exoplanets are normally interpreted as the consequence of gravitational interaction with additional bodies in the system.

Formation of starspots in self-consistent global dynamo models: Polar spots on cool stars

, 2014
Context. Observations of cool stars reveal dark spot-like features on their surfaces. Compared to sunspots, starspots can be bigger or cover a larger fraction of the stellar surface.

A Flexible Model for Investigating Properties of Starspots: Comparison of Models to Observed Data

, 2018
Cool, late-type stars have proven problematic when determining accurate age estimates for young open clusters due to inaccuracies in stellar evolution models.

On the detectability of starspot magnetic fields

The Astrophysical Journal, 1979
A starspot is here considered as the surface manifestation of a submerged magnetic dipole. It seems likely that in red dwarfs, the dipole is generated by dynamo action within the outer convection zone. As a result, a starspot-associated dipole is highly decentered.
