B fields in OB stars (BOB): on the detection of weak magnetic fields in the two early B-type stars beta CMa and epsilon CMa
L. Fossati, N. Castro, T. Morel +15
Within the context of the "B fields in OB stars (BOB)" collaboration, we used the HARPSpol spectropolarimeter to observe the early B-type stars beta CMa (HD44743; B1 II/III) and ep…
The born-again planetary nebula A78: an X-ray twin of A30
J. A. Toalá, M. A. Guerrero, H. Todt +8
We present the XMM-Newton discovery of X-ray emission from the planetary nebula (PN) A78, the second born-again PN detected in X-rays apart from A30. These two PNe share similar sp…
High-Energy Properties of the Enigmatic Be Star gamma Cassiopeiae
C. R. Shrader, K. Hamaguchi, S. J. Sturner +3
We present the results of a broad-band X-ray study of the enigmatic Be star Gamma Cassiopeiae (herein gamma Cas) based on observations made with both the Suzaku and INTEGRAL observ…
Expansion of hydrogen-poor knots in the born-again planetary nebulae A30 and A78
Xuan Fang, Martin A. Guerrero, Ramon A. Marquez-Lugo +8
We analyze the expansion of hydrogen-poor knots and filaments in the born-again planetary nebulae A30 and A78 based on Hubble Space Telescope (HST) images obtained almost 20 yr apa…
A Deep Chandra Observation of the Giant HII Region N11 I. X-ray Sources in the Field
Yael Naze, Q. Daniel Wang, You-Hua Chu +2
A very sensitive X-ray investigation of the giant HII region N11 in the LMC was performed using the Chandra X-ray Observatory. The 300ks observation reveals X-ray sources with lumi…
