Properties of PSR J1023+0038 Based on Kepler, TESS, and FAST

open access: yesThe Astrophysical Journal, 2023
The pulsar system PSR J1023+0038 is a very interesting binary with radio millisecond pulsar and low-mass X-ray binary transitions, which depend on the stellar accretion process. We have used Kepler light curves with 1 minute cadence and TESS light curves

Furnishing the Galaxy with Pulsars

open access: yes, 2007
The majority of pulsar population synthesis studies performed to date have focused on isolated pulsar evolution. Those that have incorporated pulsar evolution within binary systems have tended to either treat binary evolution poorly of evolve the pulsar ...

On the Orbital Properties of Millisecond Pulsar Binaries [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract We report a detailed analysis of the orbital properties of a binary millisecond pulsar (MSP) with a white dwarf (WD) companion. Positive correlations between the orbital period P b and eccentricity ϵ are found in two classes of MSP binaries with a He WD and with a CO/ONeMg WD, though their trends are different.

Strong binary pulsar constraints on Lorentz violation in gravity. [PDF]

open access: yesPhysical Review Letters, 2013
Binary pulsars are excellent laboratories to test the building blocks of Einstein's theory of general relativity. One of these is Lorentz symmetry, which states that physical phenomena appear the same for all inertially moving observers.

Hydrodynamics of interaction of pulsar and stellar winds and its impact on the high energy radiation of binary pulsar systems

open access: yes, 2008
The hydrodynamics of the interaction of pulsar and stellar winds in binary systems harboring a pulsar and its impact on the nonthermal radiation of the binary pulsar PSR B1259-63/SS2883 is discussed. The collision of an ultrarelativistic pulsar wind with

CHIME Discovery of a Binary Pulsar with a Massive Nondegenerate Companion

open access: yesThe Astrophysical Journal, 2023
Of the more than 3000 radio pulsars currently known, only ∼300 are in binary systems, and only five of these consist of young pulsars with massive nondegenerate companions.

CONSTRAINTS ON BLACK HOLE/HOST GALAXY CO-EVOLUTION AND BINARY STALLING USING PULSAR TIMING ARRAYS [PDF]

open access: yes, 2016
Pulsar timing arrays are now setting increasingly tight limits on the gravitational wave background from binary supermassive black holes (SMBHs). But as upper limits grow more constraining, what can be implied about galaxy evolution? We investigate which

Binary system delays and timing noise in searches for gravitational waves from known pulsars [PDF]

open access: yes, 2007
The majority of fast millisecond pulsars are in binary systems, so that any periodic signal they emit is modulated by both Doppler and relativistic effects.

A millisecond pulsar in an extremely wide binary system [PDF]

open access: yes, 2016
We report on 22 yrs of radio timing observations of the millisecond pulsar J1024−0719 by the telescopes participating in the European Pulsar Timing Array (EPTA).

Probing the properties of the pulsar wind via studying the dispersive effects in the pulses from the pulsar companion in a double neutron-star binary system [PDF]

open access: yes, 2017
The velocity and density distribution of $e^\pm$ in the pulsar wind are crucial distinction among magnetosphere models, and contains key parameters determining the high energy emission of pulsar binaries.
