X-ray irradiation of the winds in binaries with massive components [PDF]

, 2015
Binaries with hot massive components are strong X-ray sources. Besides the intrinsic X-ray emission of individual binary members originating in their winds, X-ray emission stems from the accretion on the compact companion or from wind collision.

GRB060602B = Swift J1749.4-2807: an unusual transiently accreting neutron-star X-ray binary [PDF]

, 2008
We present an analysis of the Swift BAT and XRT data of GRB060602B, which is most likely an accreting neutron star in a binary system and not a gamma-ray burst. Our analysis shows that the BAT burst spectrum is consistent with a thermonuclear flash (type-

A Unified Model for Black Hole X-Ray Binary Jets? [PDF]

, 2004
We have recently put forward a ‘unified’ semi-empirical model for the coupling between accretion and jet production in galactic black hole X-ray binaries. In this paper, we summarise this model and briefly discuss relevant considerations that have arisen

Discovery of a 2.8 s Pulsar in a 2 Day Orbit High-mass X-Ray Binary Powering the Ultraluminous X-Ray Source ULX-7 in M51 [PDF]

Astrophysical Journal, 2019
We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs (PULXs) with XMM-Newton.

A Radio Pulsar/X-ray Binary Link [PDF]

Science, 2009
From X-ray Binary to Pulsar Pulsars with millisecond rotational periods are thought to originate from neutron stars in low-mass x-ray binaries that had their spin frequencies increased by long-lasting mass transfer from their companion stars.

ASASSN-18ey: The Rise of a New Black Hole X-Ray Binary [PDF]

Astrophysical Journal, 2018
We present the discovery of ASASSN-18ey (MAXI J1820+070), a new black hole low-mass X-ray binary (LMXB) discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN).

Unveiling Properties of the Nonthermal X-Ray Production in the Gamma-Ray Binary LS 5039 Using the Long-term Pattern of Its Fast X-Ray Variability

The Astrophysical Journal, 2023
Gamma-ray binary systems, a subclass of high-mass X-ray binaries, show nonthermal emissions from radio to TeV. While efficient electron acceleration is considered to take place in them, the nature of the acceleration mechanism and the physical ...

A Comparison of Millisecond Pulsar Populations between Globular Clusters and the Galactic Field

The Astrophysical Journal, 2023
We have performed a systematic study of the rotational, orbital, and X-ray properties of millisecond pulsars (MSPs) in globular clusters (GCs) and compared their nature with those of the MSPs in the Galactic field (GF).

PSR J1953+1844 Probably Being the Descendant of an Ultracompact X-Ray Binary

The Astrophysical Journal Letters, 2023
PSR J1953+1844 (i.e., M71E) is a millisecond pulsar in a 53 minute binary orbit discovered by the Five-hundred-meter Aperture Spherical radio Telescope. The mass function from pulsar timing is 2.3 × 10 ^−7 M _⊙ .

Optical precursors to X‐ray binary outbursts [PDF]

Astronomical Notes - Astronomische Nachrichten, 2018
Disc instability models predict that for X-ray binaries in quiescence, there should be a brightening of the optical flux prior to an X-ray outburst.
