... A stellar cluster is a group of stars born at the same place, roughly at the same time, and of the same chemically homogeneous cloud of gas and dust (Karttunen et ...2003). Clusters offer useful ... See full document

... In order to identify new early-type dwarf galaxy candidates on the images, the same strategy was pursued as in the investigations of the dwarf galaxy populations in Fornax and Hydra I (Hilker et al. 2003; Mieske ... See full document

... The deformation in the disk of V354 Mon seems to change its shape at each rotational cycle, revealing a dynamical interaction between the stellar magnetosphere and the inner part of the disk [13]. Nevertheless, ... See full document

... Acoustic modes are a ff ected by the magnetic field of the star. Indeed for the Sun it has been observed (Salabert et al., 2009; Garc´ıa et al., 2013) that when magnetic activity increases the modes have lower ... See full document

... Much attention has been lavished on the transiting extrasolar planet HD 149026b (Sato et al. 2005) due to its potential to directly test models of planet formation. The planet’s small observed radius for its mass implies ... See full document

... It has been already recognized that Type I spots can act as contamination sources, but our result implies also that limb darkening coefficients can also change. This problem however can be solved in the following simple ... See full document

... Several of these clusters have been investigated using only photometric tech- niques to determine the members. As open cluster members share similar pho- tometric and kinematic properties, it is useful to complete ... See full document

... CGs included in our study, we do not detect di↵use emission from HCGs 7 and 22. From those groups detected with Chandra, only HCG 62 has emission that permeates the IGM, while HCG 42 has a bright X-ray halo centered on ... See full document
