PublicationA survey of faint, near-infrared sources towards the centre of the Galaxy
The authors present the results of a survey made at 1.65 μm (H) and 2.2 μm (K) in 15 small areas on the galactic equator between l = 0° and l = 10°. 775...
PublicationAnalysis of UV spectrophotometric observations for O-type stars
Spectral indices (delta m2100 and delta m1500) for 32 O-type stars with known spectral class and reddening are plotted versus log of effective temperature. The...
NewsAstronomers find in the Milky Way an unusual blue supergiant star travelling at high velocity
An international team of astronomers, led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has found...
PublicationResolving the Circumstellar Environment of the Galactic B[e] Supergiant Star MWC 137.II. Nebular Kinematics and Stellar Variability
The Galactic B[e] supergiant MWC 137 is surrounded by a large-scale optical nebula. To shed light on the physical conditions and kinematics of the nebula, we...
PublicationSN 1988A in M58 - A type II-P supernova with a high late-time luminosity
SN 1988A is (with exception of the well-observed SN 1987A) the only type II SN for which observations of the late tail of the light curve are presently...
PublicationThe ultraviolet spectrum of Beta Ori, B8 IA
