Evolved stars in the Local Group galaxies - II. AGB, RSG stars and dust production in IC10
F. Dell'Agli, M. Di Criscienzo, P. Ventura +4
We study the evolved stellar population of the Local Group galaxy IC10, with the aim of characterizing the individual sources observed and to derive global information on the galax…
Investigation of faint galactic carbon stars from the first Byurakan spectral survey. III. Infrared characteristics
K. S. Gigoyan, A. Sarkissian, C. Rossi +5
Infra-Red(IR) astronomical databases, namely, IRAS, 2MASS, WISE, and Spitzer, are used to analyze photometric data of 126 carbon stars whose spectra are visible in the First Byurak…
Interpreting the spectral behavior of MWC 314
A. Frasca, A. S. Miroshnichenko, C. Rossi +4
MWC 314 is one of the most luminous stars in the Milky Way. Its fundamental parameters are similar to those of LBVs, although no large photometric variations have been recorded. We…
AGB stars in the SMC: evolution and dust properties based on Spitzer observations
F. Dell'Agli, D. A. García-Hernández, P. Ventura +3
We study the population of asymptotic giant branch (AGB) stars in the Small Magellanic Cloud (SMC) by means of full evolutionary models of stars of mass 1Msun < M < 8Msun, evolved…
Oxygen rich cool stars in the Cepheus region, New observations. III
Gohar V. Petrosyan, Corinne Rossi, Silvia Gaudenzi +1
We present moderate resolution CCD spectra and R photometry for seven KP2001 stars. We revised the spectral classification of the stars in the range 3900 - 8500 A. On the bases of…
