We report the discovery of the likely white dwarf companions to radio millisecond pulsars 47 Tuc Q and 47 Tuc S in the globular cluster 47 Tucanae. These blue stars were found in near-ultraviolet images from the Hubble Space Telescope for which we de

Publikováno v: The Astrophysical Journal. 581:470-484
We report Chandra observations of the complete sample of millisecond pulsars (MSPs) with precise radio positions in the globular clusters 47Tuc (NGC104) and NGC6397. The 47Tuc MSPs are predominantly soft sources suggestive of thermal emission from sm

Publikováno v: Astrophysical Journal, 687(2), 1019-1034. IOP Publishing Ltd.
We observed the nearby, low-density globular cluster M71 (NGC 6838) with the Chandra X-ray Observatory to study its faint X-ray populations. Five X-ray sources were found inside the cluster core radius, including the known eclipsing binary millisecon

A LOW-MASS MAIN-SEQUENCE STAR AND ACCRETION DISK IN THE VERY FAINT X-RAY TRANSIENT M15 X-3
Autor: R. M. Arnason, Craig O. Heinke, H. N. Cohn, P. M. Lugger, Gregory R. Sivakoff
Publikováno v: The Astrophysical Journal. 807:52
We present near-simultaneous /Hubble Space Telescope () observations of the very faint (Lx < 1036 erg s?1) X-ray transient source M15 X-3, as well as unpublished archival observations of M15 X-3. The observations constrain the luminosity of M15 X-3 t

The BL Her stars-a class of intrinsic variable stars populating the short period (13 day) domain of the Population II instability strip-have been isolated for photometric study. The uchyP photometric indices covering the entire light cycle are report
