Abundances of 6 cool supergiants in NGC 330
NGC 330 is the brightest SMC young cluster and contains many bright supergiants. This cluster has aroused special interest, since the earlier abundance determinations indicated... -
V810 Cen Geneva photometry
The light curve of the yellow supergiant V810 Centauri in the Geneva photometric system has been analysed with Date Compensate Fourier Transform and Weighted Wavelet... -
Chemical composition of six K supergiants in the SMC
A sample of six SMC cool stars (K supergiants) are analysed by high resolution spectroscopy in order to investigate their chemical content, which should reflect that of the... -
uvby-Hbeta photometry of Eta Car 1992-94
We present and analyze two seasons of intense photometric monitoring in the Stroemgren uvbyH{beta} system of {eta} Carinae (October 1992-August 1994). The luminous blue variable... -
Radio emission from stars at 250GHz
We have used the IRAM 30 m-telescope together with the Max Planck Institute for Radio Astronomy (MPIfR) bolometer to survey nearly 270 stars of different types for 250GHz... -
BVRIJHK photometry of red LMC supergiants
(BV)J(RI)C observations for 185 and additional JHK observations for 53 red supergiant candidates in the Large Magellanic Cloud (LMC) are presented. The data have been reduced... -
Classification of Late Type Stars
Energy distributions for 33 galactic (super)giants situated mostly in the southern Milky Way in the range from 4800 to 7700 Angstroems with an effective resolution of 10... -
Abundances of Sr, Y, Zr, Ce and Ba
Sr, Y, Zr, and Ce abundances are derived for the sample of 74 cool dwarfs and subgiants with the iron abundance [Fe/H] ranged between -2.43 and 0.25. The results are based on... -
Blue and red supergiants in M33
We present a catalog of blue and red stars in M33 based on photographic photometry of over 65,000 objects extracted from plates taken with the 3.6m Canada-France-Hawaii... -
Dust extinction law in nearby galaxies. I. M31
The dust extinction laws and dust properties in M31 are explored with a sample of reddened O-type and B-type supergiants obtained from the Local Group Galaxies Survey (LGGS).... -
Period-luminosity relations of RSGs in M33 & M31
Based on previously selected preliminary samples of red supergiants (RSGs) in M33 and M31, the foreground stars and luminous asymptotic giant branch stars are further excluded,...
