Chemical analysis of early-type stars with planets
(EDP Sciences, 2021-03)
Aims. Our goal is to explore the chemical pattern of early-type stars with planets, searching for a possible signature of planet formation. In particular, we study a likely relation between the λ Boötis chemical pattern ...
A study of the effect of rotational mixing on massive stars evolution: Surface abundances of Galactic O7-8 giant stars
(EDP Sciences, 2017-03)
Context. Massive star evolution remains only partly constrained. In particular, the exact role of rotation has been questioned by puzzling properties of OB stars in the Magellanic Clouds. Aims. Our goal is to study the ...
Differential rotation in rapidly rotating early-type stars. I: motivations for combined spectroscopic and interferometric studies.
(Edp Sciences, 2011-02)
Context. Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may
exist between the convection and the internal rotation.
Aims. We explore what can be ...
A cyclic bipolar wind in the interacting binary V 393 Scorpii
(WILEY-BLACKWELLHOBOKEN, 2012-11)
V393 Scorpii is a double periodic variable characterized by a relatively stable non-orbital photometric cycle of 253 d. Mennickent et al. argue for the presence of a massive optically thick disc around the more massive ...
In-situ star formation in the outskirts of the large magellanic cloud: Gaia DR2 confirmation
(IOP Publishing, 2018-07-20)
We explore the Gaia data release 2 (DR2) proper motions of six young, main-sequence stars, members of the Large Magellanic Cloud (LMC) reported by Moni Bidin et al. These stars are located in the outskirts of the disk, ...
In-situ Star Formation in the Outskirts of the Large Magellanic Cloud: Gaia DR2 Confirmation
(Institute of Physics Publishing, 2018)
We explore the Gaia data release 2 (DR2) proper motions of six young, main-sequence stars, members of the Large Magellanic Cloud (LMC) reported by Moni Bidin et al. These stars are located in the outskirts of the disk, ...
