A Chandra Look at Five of the Broadest Double-Peaked Balmer-Line Emitters
Iskra V. Strateva, W. N. Brandt, Michael Eracleous +1
We study the 0.5-10keV emission of a sample of five of the broadest double-peaked Balmer-line emitters with Chandra. The Balmer lines of these objects originate close (within a few…
X-Ray flares in Orion Young Stars. II. Flares, Magnetospheres, and Protoplanetary Disks
Konstantin V. Getman, Eric D. Feigelson, Giuseppina Micela +3
We study the properties of powerful X-ray flares from 161 pre-main sequence (PMS) stars observed with the Chandra X-ray Observatory in the Orion Nebula region. Relationships betwee…
Very Low-Mass Objects in the Coronet Cluster: The Realm of the Transition Disks
Aurora Sicilia-Aguilar, Thomas Henning, Attila Juhász +3
We present optical and IR spectra of a set of low-mass stars and brown dwarfs in the Coronet cluster (aged ~1Myr), obtained with the multifiber spectrograph FLAMES/VLT and IRS/Spit…
Detection of X-ray Emission from the Very Old Pulsar J0108-1431
G. G. Pavlov, O. Kargaltsev, J. A. Wong +1
PSR J0108-1431 is a nearby, 170 Myr old, very faint radio pulsar near the "pulsar death line" in the P-Pdot diagram. We observed the pulsar field with the Chandra X-ray Observatory…
X-ray Observations of Parsec-Scale Tails behind Two Middle-Aged Pulsars
O. Kargaltsev, Z. Misanovic, G. G. Pavlov +2
Chandra and XMM-Newton resolved extremely long tails behind two middle-aged pulsars, J1509-5850 and J1740+1000. The tail of PSR J1509-5850 is discernible up to 5.6' from the pulsar…
Confirmation of a correlation between the X-ray luminosity and spectral slope of AGNs in the Chandra Deep Fields
C. Saez, G. Chartas, W. N. Brandt +4
We present results from a statistical analysis of 173 bright radio-quiet AGNs selected from the Chandra Deep Field-North and Chandra Deep Field-South surveys (hereafter, CDFs) in t…
