Photoevaporation and Close Encounters: How the Environment around Cygnus OB2 Affects the Evolution of Protoplanetary Disks

The Astrophysical Journal Supplement Series, 2023
In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on the evolution of protoplanetary disks orbiting around nearby young stars ...

Very massive runaway stars from three-body encounters [PDF]

, 2010
Very massive stars preferentially reside in the cores of their parent clusters and form binary or multiple systems. We study the role of tight very massive binaries in the origin of the field population of very massive stars.

Very massive stars, pair-instability supernovae and intermediate-mass black holes with the sevn code [PDF]

, 2017
Understanding the link between massive ($\gtrsim 30$ M$_{\odot{}}$) stellar black holes (BHs) and their progenitor stars is a crucial step to interpret observations of gravitational-wave events.

The Evolution of Massive Helium Stars, Including Mass Loss [PDF]

Astrophysical Journal, 2019
The evolution of helium stars with initial masses in the range 1.6–120 is studied, including the effects of mass loss by winds. These stars are assumed to form in binary systems when their expanding hydrogenic envelopes are promptly lost just after ...

A Catalog of New Slowly Pulsating B-type Stars

The Astrophysical Journal Supplement Series, 2023
This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have found 286 new slowly pulsating B-type (SPB) stars and 21 candidates.

RCW36: characterizing the outcome of massive star formation [PDF]

, 2013
Massive stars play a dominant role in the process of clustered star formation, with their feedback into the molecular cloud through ionizing radiation, stellar winds and outflows.

Understanding the Death of Massive Stars Using an Astrophysical Transients Observatory

Frontiers in Astronomy and Space Sciences, 2018
The death of massive stars, manifested as gamma-ray bursts and core-collapse supernovae, critically influence how the universe formed and evolves. Despite their fundamental importance, our understanding of these enigmatic objects is severely limited.

First HARPSpol discoveries of magnetic fields in massive stars [PDF]

, 2011
In the framework of the Magnetism in Massive Stars (MiMeS) project, a HARPSpol Large Program at the 3.6m-ESO telescope has recently started to collect high-resolution spectropolarimetric data of a large number of Southern massive OB stars in the field of

Massive runaway and walkaway stars [PDF]

Astronomy & Astrophysics, 2018
We perform an extensive numerical study of the evolution of massive binary systems to predict the peculiar velocities that stars obtain when their companion collapses and disrupts the system.

High-velocity runaway stars from three-body encounters [PDF]

, 2009
We performed numerical simulations of dynamical encounters between hard massive binaries and a very massive star (VMS; formed through runaway mergers of ordinary stars in the dense core of a young massive star cluster), in order to explore the hypothesis
