Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations

The Astrophysical Journal
Eclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.

Pulsar Signal of Deconfinement

, 1998
A solitary millisecond pulsar, if near the mass limit, and undergoing a phase transition, either first or second order, provided the transition is to a substantially more compressible phase, will emit a blatantly obvious signal---spontaneous spin-up ...

Two Coexisting Families of Compact Stars: Observational Implications for Millisecond Pulsars [PDF]

, 2017
It is usually thought that a single equation of state (EoS) model “correctly” represents cores of all compact stars. Here we emphasize that two families of compact stars, viz., neutron stars and strange stars, can coexist in nature, and that neutron ...

The second millisecond pulsar [PDF]

Nature, 1983
On the principle that no celestial object is unique, the discovery of another millisecond pulsar is overdue. That reported on page 417 has an unexpected interest.

Assessing the Role of Spin Noise in the Precision Timing of Millisecond Pulsars

, 2010
We investigate rotational spin noise (referred to as timing noise) in non-accreting pulsars: millisecond pulsars, canonical pulsars, and magnetars.

Timing of Millisecond Pulsars [PDF]

Symposium - International Astronomical Union, 1996
Arrival times of some millisecond pulsars can be measured with sub-microsecond precision. This allows unprecedented measurements of the rotation of these stars, astrometric parameters including proper motion and parallax, motion in binary and complex dynamical systems, perturbations resulting from propagation through small scale turbulence in the ...

Multiwavelength Evidence for Two New Candidate Transitional Millisecond Pulsars in the Subluminous Disk State: 4FGL J0639.1-8009 and 4FGL J1824.2+1231

The Astrophysical Journal
We report the discovery of two new Galactic accreting compact objects consistent with the respective positions of the unassociated Fermi-LAT γ -ray sources 4FGL J0639.1-8009 and 4FGL J1824.2+1231. A combination of new and archival X-ray data from Chandra,

Twenty Years of Searching for (and Finding) Globular Cluster Pulsars

, 2007
Globular clusters produce orders of magnitude more millisecond pulsars per unit mass than the Galactic disk. Since the first cluster pulsar was uncovered twenty years ago, at least 138 have been identified - most of which are binary millisecond pulsars ...

'Hidden' millisecond pulsars

The Astrophysical Journal, 1991
The radiative and hydrodynamical processes occurring near the region where the pulsar wind interacts with the material outflowing from the illuminated companion star atmosphere are addressed. The emphasis is placed on the properties of a class of 'hidden' millisecond pulsars.

Polarimetry of millisecond pulsars

The Astrophysical Journal, 1990
The mean polarization profiles of several fast pulsars were measured. Observations of pulsar PSR 1937 + 21 are similar to previously published results, except that a shallower position angle was found to swing across the pulse at low frequency; for the first time, the occurrence of orthogonal mode switching at all frequencies is explicitly demonstrated.
