Observations of UX Ori in deep minima with the Nordic Optical Telescope. I. Analysis of spectral lines
L. V. Tambovtseva, A. A. Djupvik, V. P. Grinin +11
UX Orionis stars are the most active young stars; they undergo sporadic fadings of 2 - 4 magnitudes in the V-band, due to variable circumstellar extinction caused by a nearly edge-…
Modelling UX Ori Star Eclipses based on Spectral Observations with the Nordic Optical Telescope. I. RR Tau
V. P. Grinin, L. V. Tambovtseva, A. A. Djupvik +12
Based on observations obtained with the Nordic Optical Telescope we investigate the spectral variability of the Herbig Ae star RR Tau. This star belongs to the UX Ori family, chara…
Interacting supernovae and supernova impostors. SN 2007sv: the major eruption of a massive star in UGC 5979
L. Tartaglia, A. Pastorello, S. Taubenberger +15
We report the results of the photometric and spectroscopic monitoring campaign of the transient SN 2007sv. The observables are similar to those of type IIn supernovae, a well-known…
Multiple Major Outbursts from a Restless Luminous Blue Variable in NGC 3432
A. Pastorello, M. T. Botticella, C. Trundle +16
We present new photometric and spectroscopic observations of an unusual luminous blue variable (LBV) in NGC 3432, covering three major outbursts in October 2008, April 2009 and Nov…
