The Effect of Irradiation on the Spin of Millisecond Pulsars
The Astrophysical Journal Letters, 2023 A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.

Spin frequency distributions of binary millisecond pulsars [PDF]
, 2014 Rotation-powered millisecond radio pulsars have been spun up to their present spin period by a 108−109 yr long X-ray-bright phase of accretion of matter and angular momentum in a low-to-intermediate mass binary system.

THE FORMATION OF THE ECCENTRIC-ORBIT MILLISECOND PULSAR J1903+0327 AND THE ORIGIN OF SINGLE MILLISECOND PULSARS [PDF]
The Astrophysical Journal, 2011 The millisecond pulsar J1903+0327 is accompanied by an ordinary G-dwarf star in an unusually wide ($P_{\rm orb} \simeq 95.2$\,days) and eccentric ($e \simeq 0.44$) orbit. The standard model for producing MSPs fails to explain the orbital characteristics of this extraordinary binary, and alternative binary models are unable to explain the observables ...

Scintillation velocities of five millisecond pulsars [PDF]
, 2000 Millisecond pulsars differ from normal pulsars in their mode of origin and their properties. They are thought to be born either through binary interaction or through accretion-induced collapse (AIC) of white dwarf stars.

Highlights of Astronomy, 1989 AbstractMillisecond pulsars are intrinsically interesting because they illustrate some of the most extreme physical conditions to be found anywhere in the Universe, and because their evolution exhibits several stages of great drama. It had been widely believed for several years that spin-up of an old neutron star by accretion from a close stellar ...

Searching For and Timing Millisecond Pulsars
, 2021 Millisecond pulsars are highly magnetised, rapidly rotating stellar remnants, produced in supernovae and later spun up to milisecond periods by companion stars.

The Astrophysical Journal, 2023 The timing follow-up of newly discovered millisecond pulsars (MSPs) is hindered by the larger positional uncertainty (a few tens of arcminutes) associated with the discovery.

Gravitational Radiation From Binary Systems With Time Varying Masses
Annalen der Physik, Volume 538, Issue 8, August 2026.We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Mitochondria Dictate Progressive Versus Bimodal Aging of the Mammary Gland
Aging Cell, Volume 25, Issue 8, August 2026.Breast cancer shows a bimodal age distribution with a peak at 45 and higher peak at 65. Using mice with different mitochondrial genomes, we show progressive and bimodal patterns of aging of the mammary gland with distinct pro‐tumorigenic age windows. This finding may shed light on the bimodal distribution in humans.

Magnetic fields generated by r-modes in accreting millisecond pulsars [PDF]
, 2010 In rotating neutron stars the existence of the Coriolis force allows the presence of the so-called Rossby oscillations (r-modes) which are known to be unstable to emission of gravitational waves.
