Galactic Ultracompact X-ray Binaries: Empirical Luminosities
T. F. Cartwright, M. C. Engel, C. O. Heinke +4
Ultracompact X-ray binaries (UCXBs) are thought to have relatively simple binary evolution post-contact, leading to clear predictions of their luminosity function. We test these pr…
Galactic Ultracompact X-ray Binaries: Disk Stability and Evolution
C. O. Heinke, N. Ivanova, M. C. Engel +4
We study the mass transfer rates and disk stability conditions of ultracompact X-ray binaries (UCXBs) using empirical time-averaged X-ray luminosities from Paper I (Cartwright et a…
A 2.15 Hour Orbital Period for the Low Mass X-Ray Binary XB 1832-330 in the Globular Cluster NGC 6652
Megan C. Engel, Craig O. Heinke, Gregory R. Sivakoff +2
We present a candidate orbital period for the low mass X-ray binary XB 1832-330 in the globular cluster NGC 6652 using a 6.5 hour Gemini South observation of the optical counterpar…
