Modeling non-thermal emission from SN 1987A

Autor: L. Grassitelli, Jonathan Mackey, Sean Kelly, Robert Brose, N. J. Grin

Publikováno v: Proceedings of 37th International Cosmic Ray Conference — PoS(ICRC2021).

The remnant of SN 1987A is the best-studied object of its kind. The rich data-set of its thermal and non-thermal emission across the electromagnetic spectrum poses a unique testbed for the elaboration of particle-acceleration theory. We use 2D simula

A high fraction of massive stars are found to be binaries but only a few of them are reported as photometrically variable. By studying the populations of SB2 in the 30 Doradus region, we found a subset of them that have photometry from the OGLE proje

Massive binaries (MBs) play a crucial role in the Universe. Knowing the distributions of their orbital parameters (OPs) is important for a wide range of topics, from stellar feedback to binary evolution channels, from the distribution of supernova ty

The Tarantula Massive Binary Monitoring

Publikováno v: Astronomy & Astrophysics, 634:A118. EDP Sciences

Accurate stellar parameters of individual objects in binary systems are essential to constrain the effects of binarity on stellar evolution. These parameters serve as a prerequisite to probing existing and future theoretical evolutionary models. We a

Subsonic structure and optically thick winds from Wolf--Rayet stars

Autor: Joachim M. Bestenlehner, Jonathan Mackey, N. J. Grin, L. Grassitelli, Norbert Langer, G. Graefener

Wolf-Rayet star's winds can be so dense and so optically thick that the photosphere appears in the highly supersonic part of the outflow, veiling the underlying subsonic part of the star, and leaving the initial acceleration of the wind inaccessible

The VLT-FLAMES Tarantula Survey. XXIV

Publikováno v: NASA Astrophysics Data System
Astronomy & Astrophysics, 600:A81. EDP Sciences

The Tarantula region in the Large Magellanic Cloud contains the richest population of spatially resolved massive O-type stars known so far. This unmatched sample offers an opportunity to test models describing their main-sequence evolution and mass-l

A spectroscopic analysis has been undertaken for the B-type multiple systems (excluding those with supergiant primaries) in the VLT-FLAMES Tarantula Survey (VFTS). Projected rotational velocities, $v$sin$i$, for the primaries have been estimated usin

The VLT-FLAMES Tarantula Survey XXVI: Properties of the O-dwarf population in 30 Doradus

Publikováno v: Astronomy & Astrophysics, 601:A79. EDP Sciences

The VLT-FLAMES Tarantula Survey has observed hundreds of O-type stars in the 30 Doradus region of the Large Magellanic Cloud (LMC). We study the properties of 105 apparently single O-type dwarfs. To determine stellar and wind parameters, we used the
