Results of high- and low-resolution spectral and UBV photometric observations of MWC 560 during 1990 January-October are presented. Strong variations in the star brightness compared with previously published observations are discussed. The presence o

We present evidence suggesting that the star that erupted in 1994 in the SMC multiple system HD 5980 has v sin i ~230 km s–1, which is close to the breakup velocity for this star.

We present results of IUE observations (λλ1200-3200) of the erupting system HD 5980 obtained in 1994 November and December. The 1994 spectrum presents emission lines from ions such as N III, Si II-III and Al III which were absent in 1991. There is

We report here the discovery by the Intermediate Palomar Transient Factory (iPTF) of iPTF14yb, a luminous(Mr ≈ -27.8 mag), cosmological (redshift 1.9733), rapidly fading optical transient. We demonstrate, based onprobabilistic arguments and a compa
