Abundances and density structure of the inner circumstellar ring around SN 1987A
Seppo Mattila, Peter Lundqvist, Per Groeningsson +4
We present optical spectroscopic data of the inner circumstellar ring around SN 1987A from the Anglo-Australian Telescope (AAT) and the Very Large Telescope (VLT) between ~1400 and…
Massive stars exploding in a He-rich circumstellar medium. I. Type Ibn (SN 2006jc-like) events
A. Pastorello, S. Mattila, L. Zampieri +26
We present new spectroscopic and photometric data of the type Ibn supernovae 2006jc, 2000er and 2002ao. We discuss the general properties of this recently proposed supernova family…
A Search for Very Active Stars in the Galaxy
G. Tsarevsky, J. A. De Freitas Pacheco, N. Kardashev +7
We report the first results of a systematic search near the plane of the Galaxy for the so called very active stars (VAS), which are characterized by a hard X-ray spectrum and acti…
The Iron Abundance and Density Structure of the Inner Ring around SN 1987A
S. Mattila, P. Lundqvist, P. Meikle +2
We present a spectroscopic study of the inner circumstellar ring around SN 1987A. The aim is to determine the elemental abundances and density structure, with particular emphasis o…
A search for new Galactic microquasars
G. S. Tsarevsky, E. P. Pavlenko, R. A. Stathakis +2
A complete sample of bright ROSAT sources with hard XRB-like spectra in the Galactic Plane (|b| < 15 deg.) has been tentatively identified with radio sources in the GB6/PMN/NVSS su…
Spectral Evolution of the Peculiar Ic Supernova 1998bw
R. A. Stathakis, B. J. Boyle, D. H. Jones +13
SN 1998bw holds the record for the most energetic Type Ic explosion, one of the brightest radio supenovae and probably the first supernova associated with a gamma-ray burst. In thi…
