New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems
P. Bluhm, M. I. Jones, L. Vanzi +10
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orb…
Early Dust Formation and a Massive Progenitor for SN 2011ja?
J. E. Andrews, Kelsie M. Krafton, Geoffrey C. Clayton +6
SN 2011ja was a bright (I = -18.3) Type II supernova occurring in the nearby edge on spiral galaxy NGC 4945. Flat-topped and multi-peaked H-alpha and H-beta spectral emission lines…
The substellar content of the ONC
Holger Drass, Rolf Chini, Dieter Nürnberger +5
The Substellar Initial Mass Function (SIMF) of many star-forming regions is still poorly known but the detailed knowledge of its shape will help to distinguish among the substellar…
Eclipsing high-mass binaries I. Light curves and system parameters for CPD-518946, PISMIS24-1 and HD319702
A. Barr Domínguez, R. Chini, F. Pozo Nuñez +5
We present first results of a comprehensive photometric O-star survey performed with a robotic twin refractor at the Universitätssternwarte Bochum located near Cerro Armazones in C…
The Multiplicity of High-Mass Stars
R. Chini, A. Barr, L. S. Buda +5
We report about an ongoing photometric and spectroscopic monitoring survey of about 250 O- and 540 B-type stars in the southern Milky Way with the aim to determine the fraction of…
