On the nature and evolution of the unique binary pulsar J1903+0327 by Freire, P, Bassa, C, Wex, N, Stairs, I, Champion, D, Ransom, S, Lazarus, P, Kaspi, V, Hessels, J, Kramer, M, Cordes, J, Verbiest, J, Podsiadlowski, P, Nice, D, Deneva, J, Lorimer, DR, Stappers, B, McLaughlin, M, Camilo, F

“…(abridged) PSR J1903+0327, a millisecond pulsar in an eccentric (e = 0.44) 95-day orbit with a (~ 1Msun) companion poses a challenge to our understanding of stellar evolution in binary and multiple-star systems. …”

4FGL J1318.2+6754: A Long Orbital-period Redback Candidate by Jie Lin, Hailiang Chen, Bojun Wang, Renxin Xu

The formation and properties of helium-degenerate dwarfs by Nelson, L, MacCannell, K, Davis, A

“…Moreover, many HeDD's are observed as companions in binary millisecond pulsar (BMSP) systems, and thus an accurate evaluation of their initial properties (e.g., surface temperature and luminosity) is central to the estimation of the ages of these systems.…”

A NICER View of PSR J0030+0451: Evidence for a Global-scale Multipolar Magnetic Field by Chakrabarty, Deepto

“…Recent modeling of Neutron Star Interior Composition Explorer observations of thermal X-ray pulsations from the surface of the isolated millisecond pulsar PSR J0030+0451 suggests that the hot emitting regions on the pulsar's surface are far from antipodal, which is at odds with the classical assumption that the magnetic field in the pulsar magnetosphere is predominantly that of a centered dipole. …”

Auroras on Planets around Pulsars by Ruchi Mishra, Miljenko Čemeljić, Jacobo Varela, Maurizio Falanga

“…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. In analogy with the solar system planets, we predict the existence of aurora on planets around millisecond pulsars. …”

The Intrabinary Shock and Companion Star of Redback Pulsar J2215+5135 by Andrew G. Sullivan, Roger W. Romani

“…Estimating the companion wind momentum and speed from the X-ray light curve, we find a companion mass-loss rate of ${\dot{M}}_{c}\gtrsim {10}^{-10}\,{M}_{\odot }$ yr ^−1 so that J2215 may become an isolated millisecond pulsar in ∼1 Gyr. Our X-ray analyses place constraints on the magnetization and particle density of the pulsar wind and support models of magnetic reconnection and particle acceleration in the highly magnetized relativistic IBS.…”

Redeveloping a CLEAN Deconvolution Algorithm for Scatter-broadened Radio Pulsar Signals by Olivia Young, Michael T. Lam

“…We test our improved algorithm on the highly scattered millisecond pulsar J1903+0327, showing the scattering timescale to change over years, consistent with estimates of the refractive timescale of the pulsar.…”

Searches for Gravitational Waves from Known Pulsars at Two Harmonics in 2015–2017 LIGO Data by LIGO Scientific Collaboration, Virgo Collaboration

“…For the recycled millisecond pulsar J0711-6830 our limits are only a factor of 1.3 above the spin-down limit, assuming the canonical value of 1038 kg m2 for the star's moment of inertia, and imply a gravitational-wave-derived upper limit on the star's ellipticity of 1.2 × 10-8. …”

Lower-mass-gap Black Holes in Dense Star Clusters by Claire S. Ye, Kyle Kremer, Scott M. Ransom, Frederic A. Rasio

“…This so-called lower-mass gap (LMG) was initially suggested by the lack of low-mass X-ray binary observations with accretors about 2–5 M _⊙ , but it has recently been called into question following newer observations, including an LMG candidate with a millisecond pulsar (MSP) companion in the dense globular cluster NGC 1851. …”
