Determining the Absolute Astrometric Error in Chandra Source Catalog Positions
Arnold H. Rots, Tamas Budavari
Although relative errors can readily be calculated, the absolute astrometric accuracy of the source positions in the Chandra Source Catalog (CSC), Version 1.0, is a priori unknown.…
The Super-Soft X-ray Phase of Nova RS Ophiuchi 2006
J. P. Osborne, K. L. Page, A. P. Beardmore +13
Swift X-ray observations of the ~60 day super-soft phase of the recurrent nova RS Ophiuchi 2006 show the progress of nuclear burning on the white dwarf in exquisite detail. First s…
A quick test of the WEP enabled by a sounding rocket
Robert D. Reasenberg, Enrico C. Lorenzini, Biju R. Patla +4
We describe SR-POEM, a Galilean test of the weak equivalence principle, which is to be conducted during the free fall portion of a sounding rocket flight. This test of a single pai…
The ELM Survey. I. A Complete Sample of Extremely Low Mass White Dwarfs
Warren R. Brown, Mukremin Kilic, Carlos Allende Prieto +1
We analyze radial velocity observations of the 12 extremely low-mass <0.25 Msol white dwarfs (WDs) in the MMT Hypervelocity Star Survey. Eleven of the 12 WDs are binaries with orbi…
X-ray emission processes in stars
Paola Testa
A decade of X-ray stellar observations with Chandra and XMM-Newton has led to significant advances in our understanding of the physical processes at work in hot (magnetized) plasma…
A Galactic Center Origin for HE 0437-5439, the Hypervelocity Star near the Large Magellanic Cloud
Warren R. Brown, Jay Anderson, Oleg Y. Gnedin +4
We use Hubble Space Telescope imaging to measure the absolute proper motion of the hypervelocity star (HVS) HE 0437-5439, a short-lived B star located in the direction of the Large…
