Hard X-ray emissions from the Herbig Be star MWC 297 were discovered in three separate observations spanning 5 days in 1994 April with the Advanced Satellite for Cosmology and Astrophysics (ASCA). An X-ray flare was found at the beginning of the second observation with a maximum luminosity of ≈4.9 × 1032 ergs s-1, which is 5 times larger than that of the quiescent phase (the first observation). It then declined with an e-folding time of ≈5.6 × 104 s to the preflare level in the third…

X-Ray Study of Herbig Ae/Be Stars

We present ASCA results of intermediate-mass pre-main-sequence (PMS) stars, or Herbig Ae/Be (HAeBe) stars. Among the 35 ASCA pointed sources, we detect 11 plausible X-ray counterparts. X-ray

The Herbig Ae Star HD 163296 in X-Rays

Chandra X-ray imaging spectroscopy of the nearby Herbig Ae star HD 163296 at 100 AU angular resolution is reported. A pointlike, soft (kT ~ 0.5 keV), emission-line source is detected at the location

X-Ray-emitting Young Stars in the Orion Nebula

The Orion Nebula Cluster and the molecular cloud in its vicinity have been observed with the ACIS-I detector on board the Chandra X-ray Observatory with 23 hr exposure in two observations. We detect

A large X-ray flare from the Herbig Ae star V892 Tau

We report the XMM-Newton observation of a large X-ray flare from the Herbig Ae star V892 Tau. The apparent low mass companion of V892 Tau, V892 Tau NE, is unresolved by XMM-Newton. Nevertheless there

X-ray Flares Observed from Six Young Stars Located in the Region of Star Clusters NGC 869 and IC 2602

We present, for the first time, an analysis of seven intense X-ray flares observed from six stars (LAV 796, LAV 1174, SHM2002 3734, 2MASS 02191082+5707324, V553 Car, V557 Car). These stars are

X-Ray and Infrared Observations of Embedded Young Stars in NGC 2264

Images of the NGC 2264 star-forming region, which we have acquired with the XMM-Newton spacecraft, reveal strong X-ray emission from three deeply embedded (AV ≥ 10 mag) young stellar objects in the

Large X-ray Flares on Stars Detected with MAXI/GSC: A Universal Correlation between the Duration of a Flare and its X-ray Luminosity

23 giant flares from 13 active stars (eight RS CVn systems, one Algol system, three dMe stars and one YSO) were detected during the first two years of our all-sky X-ray monitoring with the gas

The Sun as an X-Ray Star. III. Flares

In previous works we have developed a method to convert solar X-ray data, collected with the Yohkoh/SXT, into templates of stellar coronal observations. Here we apply the method to several solar

Chandra observations of a young embedded magnetic B star

This paper reports on an analysis of two Chandra X-ray observations of the young magnetic B starOphiuchus S1. X-ray emission from the star was detected in both observations. The average flux was

Chandra X-ray observations of the stellar group near the Herbig Be star MWC 297 A revision of the X-ray properties of MWC 297

We present a Chandra ACIS-I X-ray observation of the region near the Herbig early-Be star MWC 297, where we detect a tight group of point X-ray sources. These are probably physically associated to



A giant X-ray flare on Lambda Eridani (B2e)

A 30 ks observation with the ROSAT PSPC distributed over 39 hr shows that the putatively single, mild B2e star Lambda Eri emits at most times a soft X-ray flux at a rate and temperature consistent

Hot massive stars represent only a small fraction of the stellar population of the galaxy, but their enormous luminosities make them visible over large distances. Therefore, they are ideal standard
