Three - micron spectra of AGB stars and supergiants in nearby galaxies ⋆
The dependence of stellar molecular bands on the metallicity is studied using infrared L-band spectra of AGB stars (both carbon-rich and oxygen-rich) and M-type supergiants in the Large and Small Magellanic Clouds (LMC and SMC) and in the Sagittarius Dwarf Spheroidal Galaxy. The spectra cover SiO bands for oxygen-rich stars, and acetylene (C 2 H 2), CH and HCN bands for carbon-rich AGB stars. T...
متن کاملStar Formation in Three Nearby Galaxy Systems
We present an analysis of the distribution and strength of star formation in three nearby small galaxy systems, which are undergoing a weak interaction, a strong interaction, and a merging process, respectively. The galaxies in all systems present widespread star formation enhancements, as well as, in some cases, nuclear activity. In particular, for the two closest systems, we study the numberc...
متن کاملObservational investigation of mass loss of M supergiants
We present the analysis of infrared photometry and millimeter spectroscopy of a sample of 74 late-type supergiants. These observations are particularly suitable to study the mass loss and the circumstellar envelopes of evolved massive stars. In particular, we quantify the circumstellar infrared excess, the relation of mass loss with stellar properties, using the K-[12] colour index as mass-loss...
متن کاملSpectroscopic study of the variability of three northern Of supergiants
The transition from early Of stars to WN type objects is poorly understood. O-type supergiants with emission lines (OIf) are considered to be intermediate between these two classes. The scope of this paper is to investigate the spectral variability of three Of supergiants. We constituted spectral time series of unprecedented quality for our targets (∼ 200 spectra in total), essentially in the b...
متن کاملLong Secondary Periods in Variable Red Giants
We present a study of a sample of LMC red giants exhibiting Long Secondary Periods (LSPs). We use radial velocities obtained from VLT spectral observations and MACHO and OGLE light curves to examine properties of the stars and to evaluate models for the cause of LSPs. This sample is much larger than the combined previous studies of Hinkle et al. (2002) and Wood, Olivier & Kawaler (2004). Binary...
