EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Westerlund 1 and 2 Open Clusters Survey
M. G. Guarcello, E. Flaccomio, J. F. Albacete-Colombo +48
Context. With a mass exceeding several 10^4 solar masses and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming…
Pre-main-sequence stars in the young open cluster NGC 1893: II. Evidence for triggered massive star formation
Ignacio Negueruela, Amparo Marco, GianLuca Israel +1
(Abridged) The open cluster NGC 1893, illuminating the HII region IC410, contains a moderately large population of O-type stars and is one of the youngest clusters observable in th…
The Be/X-ray transient KS 1947+300
Ignacio Negueruela, GianLuca Israel, Amparo Marco +2
We present optical spectroscopy and optical and infrared photometry of the counterpart to the transient X-ray source KS 1947+300. The counterpart is shown to be a moderately redden…
The discovery and study of the optical counterparts of the transient X-ray pulsars RXJ0052.1-7319 and XTEJ0111.2-7317 in the SMC
Stefano Covino, Ignacio Negueruela, Sergio Campana +4
We report on the discovery and confirmation of the optical counterparts of the two transient X-ray pulsars, RXJ0052.1-7319 and XTEJ0111.2-7317. In the narrow (~3" radius) X-ray err…
