Spots, plages, and flares on lambda Andromedae and II Pegasi
TL;DR: In this article, the authors present the results of a contemporaneous photometric and spectroscopic monitoring of lambda And and II Peg aimed at investigating the behavior of surface inhomogeneities in the atmospheres of these active stars which have nearly the same temperature but different gravity.
A New Method for Classifying Flares of UV Ceti Type Stars: Differences Between Slow and Fast Flares
Hasan Ali Dal,S. Evren +1 more
TL;DR: In this article, a new method is presented to classify flares derived from the photoelectric photometry of UV Ceti type stars, based on statistical analyses using an independent samples t-test.
