The Disk Veiling Effect of the Black Hole Low-Mass X-ray Binary A0620-00

Wan-Min Zheng, Qiaoya Wu, Jianfeng Wu +15

The optical light curves of quiescent black hole low-mass X-ray binaries often exhibit significant non-ellipsoidal variabilities, showing the photospheric radiation of the companio…

A Swift study of long-term changes in the X-ray flaring properties of Sagittarius A*

A. Andrés, J. van den Eijnden, N. Degenaar +12

The radiative counterpart of the supermassive black hole at the Galactic Centre, Sagittarius A*, displays flaring emission in the X-ray band atop a steady, quiescent level. Flares…

A Spectroscopic Angle on Central Engine Size Scales in Accreting Neutron Stars

Nicolas Trueba, J. M. Miller, A. C. Fabian +9

Analyses of absorption from disk winds and atmospheres in accreting compact objects typically treat the central emitting regions in these systems as point sources relative to the a…

Five new hot-Jupiter transits investigated with Swift-UVOT

Lia Corrales, Sasikrishna Ravi, George W. King +3

Short wavelength exoplanet transit measurements have been used to probe mass-loss in exoplanet atmospheres. We present the Swift-UVOT transit light curves for five hot Jupiters orb…

Measuring the Density Structure of an Accretion Hot Spot

C. C. Espaillat, C. E. Robinson, M. M. Romanova +5

Magnetospheric accretion models predict that matter from protoplanetary disks accretes onto the star via funnel flows which follow the stellar field lines and shock on the stellar…

A new radio census of neutron star X-ray binaries

J. van den Eijnden, N. Degenaar, T. D. Russell +16

We report new radio observations of a sample of thirty-six neutron star (NS) X-ray binaries, more than doubling the sample in the literature observed at current-day sensitivities.…
