X-ray Emission from O Stars [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractYoung O stars are strong, hard, and variable X-ray sources; properties that strongly affect their circumstellar and galactic environments. After ≈ 1 Myr, these stars settle down to become steady sources of soft X-rays. I will use high-resolution X-ray spectroscopy and MHD modeling to show that young O stars like θ1 Ori C are well explained by ...

The X-Ray View of the Wolf-Rayet Stars [PDF]
Symposium - International Astronomical Union, 1995 Ever since the earliest work, X-ray observations have been central in the chequered development of the study of interacting high-velocity winds in binaries. This review assesses how confidently the observations of Wolf-Rayet stars may be interpreted as the result of colliding winds, drawing attention to the wide range of X-ray luminosities even among ...

X-Rays from Stars and Planetary Systems [PDF]
, 2019 The Chandra X-ray Observatory has completed a remarkable twenty years in orbit. A large part of the science program of Chandra during this time has involved the study of stars and their planetary systems. This primer aims to give the reader a taste of the enormous range of stellar and planetary astrophysics that Chandra has enabled.

Ultraluminous X-ray sources and star formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 Chandra observations of the Cartwheel galaxy reveal a population of ultraluminous X-ray sources (ULXs) with lifetimes < 10^7 yr associated with a spreading wave of star formation which began some 3 x 10^8 yr ago. A population of high-mass X-ray binaries provides a simple model: donor stars of initial masses M_2 > 15 Msun transfer mass on their ...

X-ray observations of isolated neutron stars
Proceedings of Multifrequency Behaviour of High Energy Cosmic Sources XIV — PoS(MULTIF2023)Pulsars are rapidly spinning neutron stars, that radiate at the expense of their strong magnetic field and their high surface temperature. Five decades of multi-wavelength observations showed a large variety of physical parameters, such as the spin period, the magnetic field and the age, and of observational properties, especially in the radio and X ...
