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-…
Planet Hunters TESS IV: A massive, compact hierarchical triple star system TIC 470710327
Nora L. Eisner, Cole Johnston, Silvia Toonen +37
We report the discovery and analysis of a massive, compact, hierarchical triple system (TIC 470710327) initially identified by citizen scientists in data obtained by NASA's Transit…
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…
