Maser, infrared and optical emission for late-type stars in the Galactic plane [PDF]

, 2017
Radio astrometric campaigns using VLBI have provided distances and proper motions for masers associated with young massive stars (BeSSeL survey). The ongoing BAaDE project plans to obtain astrometric information of SiO maser stars located in the inner ...

Massive stars in transition [PDF]

EAS Publications Series, 2004
We discuss the various post-main sequence phases of massive stars, focusing on Wolf-Rayet stars, Luminous Blue Variables, plus connections with other early-type and late-type supergiants. End states for massive stars are also investigated, emphasising connections between Supernovae originating from core-collapse massive stars and Gamma Ray Bursts.

Massive stars in the giant molecular cloud G23.3−0.3 and W41 [PDF]

, 2014
Context. Young massive stars and stellar clusters continuously form in the Galactic disk, generating new Hii regions within their natal giant molecular clouds and subsequently enriching the interstellar medium via their winds and supernovae.Aims. Massive

Properties of massive stars in four clusters of the VVV survey

, 2015
The evolution of massive stars is only partly understood. Observational constraints can be obtained from the study of massive stars located in young massive clusters.

On the ongoing multiple blowout in NGC 604 [PDF]

, 2000
Several facts regarding the structure of NGC 604 are examined here. The three main cavities, produced by the mechanical energy from massive stars which in NGC 604 are spread over a volume of 10$^6$ pc$^3$, are shown here to be undergoing blowout into the

Evolution of Massive Population III Stars

Acta Polytechnica CTU Proceedings, 2014
While the evolution of massive stars in the local Universe is dominated by mass-loss, the evolution of massive Population III stars should be dominated by rotation.

Hypervelocity binary stars: smoking gun of massive binary black holes

, 2007
The hypervelocity stars recently found in the Galactic halo are expelled from the Galactic center through interactions between binary stars and the central massive black hole or between single stars and a hypothetical massive binary black hole.

Turbulence-supported Massive Star Envelopes

The Astrophysical Journal Letters, 2023
Abstract The outer envelopes of massive (M ≳ 10 M ⊙) stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and helium) that trigger near-surface convection zones.

Optical and Infrared Counterparts of the X-Ray Sources Detected in the Chandra Cygnus OB2 Legacy Survey

The Astrophysical Journal Supplement Series, 2023
The young massive OB association Cygnus OB2, in the Cygnus X complex, is the closest (∼1400 pc) star-forming region to the Sun hosting thousands of young low-mass stars and up to 1000 OB stars, among which are some of the most massive stars known in our ...
