We report on the properties of 11 early B stars observed with gratings on board XMM-Newton and Chandra, thereby doubling the number of B stars analysed at high resolution. The spectra typically appear soft, with temperatures of 0.2--0.6 keV, and moderately bright (log[L_{X}/L_{BOL}]~ -7) with lower values for later type stars. In line with previous studies, we also find an absence of circumstellar absorption, negligible line broadening, no line shift, and formation radii in the range 2 - 7 R…

Shock-heated radiation-driven outflows as a solution to the weak-wind problem of late O-type stars
Context. Radiation-driven mass loss is key to our understanding of massive-star evolution. However, for low-luminosity O-type stars there are big discrepancies between theoretically predicted and


Hot stars observed by XMM-Newton - I. The catalog and the properties of OB stars
Aims. Following the advent of increasingly sensitive X-ray observatories, deep observations of early-type stars became possible. However, the results for only a few objects or clusters have until now
X-ray emission from magnetic massive stars
Magnetically confined winds of early-type stars are expected to be sources of bright and hard X-rays. To clarify the systematics of the observed X-ray properties, we have analyzed a large series of
High-resolution X-Ray Spectroscopy of the Magnetic Of?p Star HD?148937
High-resolution data of the peculiar magnetic massive star HD 148937 were obtained with Chandra-HETGS, and are presented here in combination with a re-analysis of the older XMM-RGS data. The lines of
XMM-Newton observations of β Centauri (B1 III): The temperature structure in the hot plasma and the photosphere-wind connection
We present XMM-Newton observations of the B giant β Centauri (Bl III). The spectra are rich of spectral lines from a wide range of ionization stages which indicate temperatures in the range ∼0.1-0.6
ROSAT PSPC Observations of 27 Near-Main-Sequence B Stars
In this paper, we report on ROSAT Position Sensitive Proportional Counter (PSPC) observations of 27 near-main-sequence B stars made with unprecedented sensitivity. Contrary to the results of previous
Motivated by recent detections by the XMM and Chandra satellites of X-ray line emission from hot, luminous stars, we present synthetic line pro—les for X-rays emitted within parameterized models of a
Chandra spectroscopy of the hot star β Crucis and the discovery of a pre-main-sequence companion
In order to test the O star wind-shock scenario for X-ray production in less luminous stars with weaker winds, we made a pointed 74-ks observation of the nearby early B giant, β Crucis (β Cru; B0.5
gamma Cassiopeiae: an X-ray Be star with personality
An exciting unsolved problem in the study of high energy processes of early type stars concerns the physical mechanism for producing X-rays near the Be starγ Cassiopeiae. By now we know that this
An Extensive Collection of Stellar Wind X-Ray Source Region Emission Line Parameters, Temperatures, Velocities, and Their Radial Distributions as Obtained from Chandra Observations of 17 OB Stars
Chandra high energy resolution observations have now been obtained from numerous nonpeculiar O and early B stars. The observed X-ray emission line properties differ from prelaunch predictions, and
Fundamental properties of nearby single early B-type stars
Fundamental parameters of a sample of 26 apparently slowly-rotating single early B-type stars in the solar neighbourhood are presented and compared to high-precision data from detached eclipsing
