Stellar Chromospheric Activity [PDF]
Living Reviews in Solar Physics, 2008 The Sun, stars similar to it, and many rather dissimilar to it, have chromospheres, regions classically viewed as lying above the brilliant photosphere and characterized by a positive temperature gradient and a marked departure from radiative equilibrium.

Stellar magnetic activity and exoplanets [PDF]
EPJ Web of Conferences, 2017 It has been proposed that magnetic activity could be enhanced due to interactions between close-in massive planets and their host stars. In this article, I present a brief overview of the connection between stellar magnetic activity and exoplanets ...

The stellar activity‐rotation relationship [PDF]
Astronomische Nachrichten, 2013 Using a new catalog of 824 solar and late-type stars with measured X-ray luminosities and rotation periods we have studied the relationship between rotation and stellar activity that is believed to be a probe of the underlying stellar dynamo.

Inferences on Stellar Activity and Stellar Cycles from Asteroseismology
Space Science Reviews, 2014 The solar activity cycle can be studied using many different types of observations, such as counting sunspots, measuring emission in the Ca II H&K lines, magnetograms, radio emissions, etc. One of the more recent ways of studying solar activity is to
