Journal ArticleDOI
The 2006 hot phase of Romano's star (GR 290) in M33
TL;DR: In this article, the authors investigated the long term, S Dor-type variability of the luminous blue variable GR290 (Romano's star) in M33, and its 2006 minimum phase.
Journal ArticleDOI
The horizontal branch morphology of M31 globular clusters. Extreme second parameter effect in outer halo clusters
S. Perina,Michele Bellazzini,Alberto Buzzoni,Carla Cacciari,Luciana Federici,F. Fusi Pecci,S. Galleti +6 more
TL;DR: In this paper, a simplified version of the Mironov index (SMI; B/(B+R) ) is used to parametrize the horizontal branch (HB) morphology for 23 globular clusters in the M31 galaxy.
