Modulated Gamma-ray emission from compact millisecond pulsar binary systems [PDF]

, 2013
A significant amount of the millisecond pulsars has been discovered within binary systems. In several such binary systems the masses of the companion stars have been derived allowing to distinguish two classes of objects, called the Black Widow and the ...

SAX J1808.4-3658, an accreting millisecond pulsar shining in gamma rays? [PDF]

, 2015
We report the detection of a possible gamma-ray counterpart of the accreting millisecond pulsar SAX J1808.4-3658. The analysis of ~6 years of data from the Large Area Telescope on board the Fermi Gamma-ray Space Telescope (Fermi-LAT) within a region of ...

Swings between rotation and accretion power in a millisecond binary pulsar [PDF]

, 2013
It is thought that neutron stars in low-mass binary systems can accrete matter and angular momentum from the companion star and be spun-up to millisecond rotational periods.

Multi-Messenger Astrophysics of a Millisecond Pulsar Orbiting around a Massive Black Hole

Universe, 2022
Extreme-mass-ratio and intermediate-mass-ratio binaries with a millisecond pulsar are gravitational-wave sources that emit also electromagnetic radiation.

Auroras on Planets around Pulsars

The Astrophysical Journal Letters, 2023
The first extrasolar planets were discovered serendipitously, by finding the slight variation in otherwise highly regular timing of the pulses, caused by the planets orbiting a millisecond pulsar.

Discovery and Timing Analysis of New Pulsars in Globular Cluster NGC 5024: New Observations from FAST

The Astrophysical Journal Letters, 2023
The most distant globular cluster (GC) with known pulsars is NGC 5024 (M53). In this paper, we report the discovery of a new binary millisecond pulsar, PSR J1312+1810E (M53E), and present the new timing solutions for M53B–E based on 22 observations from ...

A Light Redback Companion of PSR J1622–0315 and Irradiation Power in Spider Systems

The Astrophysical Journal, 2023
We report optical observations of the millisecond pulsar binary system PSR J1622–0315 with the Lulin 1 m telescope in Taiwan and the Lijiang 2.4 m telescope in China between 2019 and 2021.

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 _⊙ .

Description and Application of the Surfing Effect

Universe, 2022
The standard technique for very low-frequency gravitational wave detection is mainly based on searching for a specific spatial correlation in the variation of the times of arrival of the radio pulses emitted by millisecond pulsars with respect to a ...
