HD 271791: dynamical versus binary-supernova ejection scenario
The atmosphere of the extremely high-velocity (530 − 920 km s) early B-type star HD271791 is enriched in α-process elements, which suggests that this star is a former secondary component of a massive tight binary system and that its surface was polluted by the nucleosynthetic products after the primary star exploded in a supernova. It was proposed that the (asymmetric) supernova explosion unbin...
متن کاملBoron in the extreme Pop II star HD 140283 and the production of light elements in the Early Galaxy ⋆
Using observations of the 2496.7 Å B i line with the HST GHRS at a nominal resolution of 90,000, we have found the abundance of boron of HD140283 to be log ǫB(= 12 + log(NB/NH)) = 0.34 ± 0.20. This result is found when a significant non-LTE effect in the formation of the B i line is taken into account. The resulting NB/NBe ratio is about 17 (in the range 9 – 34), which is in very good agreement...
متن کاملIs the bowshock of the runaway massive star HD 195592 a Fermi source?
Context. HD 195592 is an O-type super-giant star, known as a well-established runaway. Recently, a Fermi γ-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 195592 has been reported. Aims. Our goal is to explore the scenario where HD 195592 is the counterpart of the Fermi γ-ray source, modeling the non-thermal emission produced in the bowshock of the runaway star. Method...
متن کاملA runaway collision in a young star cluster as the origin of the brightest supernova.
Supernova SN 2006gy in the galaxy NGC 1260 is the most luminous recorded. Its progenitor might have been a very massive (>100 Mo, where is the mass of the Sun) star, but that interpretation is incompatible with hydrogen in the spectrum of the supernova; stars >40 Moare believed to have shed their hydrogen envelopes several hundred thousand years before the explosion. Alternatively, the progenit...
متن کاملNeutrinos from Pre-supernova Star *
Analysis of the massive star properties during C, Ne, O & Si burning i.e. the neutrino-cooled stage, leads to the simplified neutrino emission model. In the framework of this model we have simulated spectrum of the antineutrinos. Flux normalized according to the massive star model with explicitly given neutrino luminosity allow us to predict signal produced in water Cherenkov detectors. The res...
