Co-existence and switching between fast and Omega-slow wind solutions in rapidly rotating massive stars
(OXFORD UNIV PRESS, 2018)Most radiation-driven winds of massive stars can be modelled with m-CAK theory, resulting in the so-called fast solution. However, the most rapidly rotating stars among them, especially when the rotational speed is higher ... -
Galactic or extragalactic chemical tagging for NGC3201? Discovery of an anomalous CN-CH relation
(EDP SCIENCES S A, 2018)Context. The origin of the globular cluster (GC) NGC 3201 is under debate. Its retrograde orbit points to an extragalactic origin, but no further chemical evidence supports this idea. Light-element chemical abundances are ... -
Influence of porosity on high-velocity mass-asymmetric collisions
(OXFORD UNIV PRESS, 2020)Using granular mechanics, we study the influence of porosity on the collisions of spherical granular aggregates with a mass ratio of around 60. At high filling factors, the projectile produces a crater on the target, similar ... -
Spectroscopic and photometric study of the eclipsing interacting binary V495 Centauri
(OXFORD UNIV PRESS, 2018)Double Periodic Variables (DPV) are among the new enigmas of semidetached eclipsing binaries. These are intermediate-mass binaries characterized by a long photometric period lasting on average 33 times the orbital period. ...
