Bona-fide, Strong-variable Galactic Luminous Blue Variable Stars Are Fast Rotators: Detection of a High Rotational Velocity in Hr Carinae
We report optical observations of the Luminous Blue Variable (LBV) HR Carinae which show that the star has reached a visual minimum phase in 2009. More importantly, we detected absorptions due to Si IV λλ4088–4116. To match their observed line profiles from 2009 May, a high rotational velocity of vrot ≃ 150± 20 km s −1 is needed (assuming an inclination angle of 30), implying that HR Car rotate...
متن کاملA newly identified Luminous Blue Variable in the galactic starburst cluster Westerlund 1
We present observations of the massive transitional star W243 in Westerlund 1. We find an apparent spectral type of early-mid A from our data, in contrast to an earlier classification of B2I, made from data obtained in 1981. The concurrent development of a rich emission line spectrum suggests a very high mass loss rate; the continued presence of He i emission suggesting that the underlying star...
متن کاملFiat and Bona Fide Boundaries
There is a basic distinction, in the realm of spatial boundaries, between bona fide boundaries on the one hand, and fiat boundaries on the other. The former are just the physical boundaries of old. The latter are exemplified especially by boundaries induced through human demarcation, for example in the geographic domain. The classical problems connected with the notions of adjacency, contact, s...
متن کاملThe Birth - Cluster of the Galactic Luminous Blue Variable WRA 751 ⋆
We present the results of NTT/VLT U BV imaging of a 260 arcmin 2 region containing the Galactic Luminous Blue Variable WRA 751, in search for its birth-cluster, i.e. a cluster of young and massive stars spatially and physically associated with it. On the basis of the classical reddening-free parameter Q, we have identified a sample of 24 early-type stars with colours typical of spectral types e...
متن کاملWhat Are the bona fide GSK3 Substrates?
Nearly 100 proteins are proposed to be substrates for GSK3, suggesting that this enzyme is a fundamental regulator of almost every process in the cell, in every tissue in the body. However, it is not certain how many of these proposed substrates are regulated by GSK3 in vivo. Clearly, the identification of the physiological functions of GSK3 will be greatly aided by the identification of its bo...
