Mass Segregation in Young Magellanic Clouds Star Clusters: Four Clusters observed with HST
D. Gouliermis, S. C. Keller, M. Kontizas +2
We present the results of our investigation on the phenomenon of mass segregation in young star clusters in the Magellanic Clouds. HST/WFPC2 observations on NGC 1818, NGC 2004 & NG…
Blue Variable Stars from the MACHO database I: Photometry and Spectroscopy of the LMC sample
Stefan C. Keller, M. S. Bessell, K. H. Cook +2
We present the photometric properties of 1279 blue variable stars within the LMC. Photometry is derived from the MACHO database. The lightcurves of the sample exhibit a variety of…
Pristine CNO abundances from Magellanic Cloud B stars I. The LMC cluster NGC 2004 with UVES
A. J. Korn, S. C. Keller, A. Kaufer +4
We present chemical abundances for four main sequence B stars in the young cluster NGC 2004 in the Large Magellanic Cloud (LMC). Apart from H II regions, unevolved OB-type stars ar…
The MACHO Project LMC Variable Star Inventory: XII. Three Cepheid Variables in Eclipsing Binaries
C. Alcock, R. A. Allsman, D. R. Alves +22
We present a method for solving the lightcurve of an eclipsing binary system which contains a Cepheid variable as one of its components as well as the solutions for three eclipsing…
Discovery of pulsations from the Be/X-ray binary RX J0101.3-7211 in the SMC by XMM-Newton
M. Sasaki, F. Haberl, S. Keller +1
We report pulsations in the X-ray flux of RX J0101.3-7211 in the Small Magellanic Cloud (SMC) with a period of 455+/-2 s in XMM-Newton EPIC-PN data. The X-ray spectrum can be descr…
