Green Bank Telescope Discovery of the Redback Binary Millisecond Pulsar PSR J0212+5321
The Astrophysical Journal, 2023 We report the discovery of a 2.11 ms binary millisecond pulsar during a targeted search of the redback optical candidate coincident with the γ -ray source 3FGL J0212.5+5320 using the Robert C.

Orbital eccentricity of binary radio pulsars in globular clusters and interaction between stars
, 2009 We analyze the observed distribution of the orbital eccentricity and period of binary radio pulsars in globular clusters using computational tools to simulate binary-single star interactions.

The detectability of eccentric binary pulsars [PDF]
, 2013 Studies of binary pulsars provide insight into various theories of physics. Detection of such systems is challenging due to the Doppler modulation of the pulsed signal caused by the orbital motion of the pulsar. We investigated the loss of sensitivity in

Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

, 2004 The first eclipsing binary pulsar, PSR B1957+20, was discovered in 1987. Since then, 13 other eclipsing low-mass binary pulsars have been found, 12 of these are in globular clusters. In this paper we list the known eclipsing binary pulsars and their properties, with special attention to the eclipsing systems in 47 Tuc.

Constraints on Natal Pulsar Kicks from Eccentric Binary Pulsars [PDF]
The Astrophysical Journal, 1999 We investigate the expected space velocities and misalignment angles of the eccentric binary pulsars for a range of possible progenitor systems and natal kick models. In particular, the effect of the orbital separation at the instant of supernova is discussed.

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade
Radio Science, Volume 60, Issue 7, July 2025.Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Pulsar magnetospheres in binary systems
The Astrophysical Journal, 1985 The criterion for stability of a tangential discontinuity interface in a magnetized, perfectly conducting inviscid plasma is investigated by deriving the dispersion equation including the effects of both gravitational and centrifugal acceleration. The results are applied to neutron star magnetospheres in X-ray binaries. The Kelvin-Helmholtz instability
