Hubble Space Telescope and Ground-Based Observations of SN 1993J and SN 1998S: CNO Processing in the Progenitors
Claes Fransson, Peter M. Challis, Roger A. Chevalier +13
Ground-based and Hubble Space Telescope observations are presented for SN 1993J and SN 1998S. SN 1998S shows strong, relatively narrow circumstellar emission lines of N III-V and C…
Diffuse Interstellar Bands in NGC 1448
Jesper Sollerman, Nick Cox, Seppo Mattila +4
We present spectroscopic VLT/UVES observations of two emerging supernovae, the Type Ia SN 2001el and the Type II SN 2003hn, in the spiral galaxy NGC 1448. Our high resolution and h…
The late-time light curve of the Type Ia supernova 2000cx
Jesper Sollerman, Jan Lindahl, Cecilia Kozma +10
We have conducted a systematic and comprehensive monitoring programme of the Type Ia supernova 2000cx at late phases using the VLT and HST. The VLT observations cover phases 360 to…
The young pulsar PSR B0540-69.3 and its synchrotron nebula in the optical and X-rays
N. I. Serafimovich, Yu. A. Shibanov, P. Lundqvist +1
The young PSR B0540-69 (B0540) in the LMC is the only pulsar (except the Crab pulsar) for which a near-UV spectrum has been obtained. However, the absolute flux and spectral index…
The type IIn supernova 1994W: evidence for the explosive ejection of a circumstellar envelope
Nikolai N. Chugai, Sergei I. Blinnikov, Robert J. Cumming +6
We present and analyse spectra of the Type IIn supernova 1994W obtained between 18 and 203 days after explosion. During the luminous phase (first 100 d) the line profiles are compo…
On the source of the late-time infrared luminosity of SN 1998S and other type II supernovae
M. Pozzo, W. P. S. Meikle, A. Fassia +4
We present late-time near-infrared (NIR) and optical observations of the type IIn SN 1998S. The NIR photometry spans 333-1242 days after explosion, while the NIR and optical spectr…
