Exploring the optical properties of redback pulsars: The case of J1717+4308A in the globular cluster M92
Jianxing Chen, Greta Ettorre, Cristina Pallanca +13
Binary millisecond pulsars (MSPs) in globular clusters (GCs) are key for binary and stellar evolution studies under extreme conditions. The identification of their optical companio…
An energy approach to pulsar-disc interaction: disc stability and implications for transitional millisecond pulsars
Eda Vurgun, Domingo GarcÃa-Senz, Manuel Linares +1
The stability of an accretion disc surrounding a millisecond pulsar is analysed from an energetic point of view, using magnetohydrodynamic simulations that consider realistic disc…
Jet break revealed in the transitional millisecond pulsar candidate 4FGL J0427.8-6704
K. I. I. Koljonen, M. Linares, J. C. A. Miller-Jones
Understanding the formation and properties of relativistic jets from accreting compact objects has far-reaching implications in astrophysics. Transitional millisecond pulsars (tMSP…
Discovery of the variable optical counterpart of the redback pulsar PSR J2055+1545
Marco Turchetta, Bidisha Sen, Jordan A. Simpson +5
We present the discovery of the variable optical counterpart to PSR J2055+1545, a redback millisecond pulsar, and the first radial velocity curve of its companion star. The multi-b…
Investigating cannibalistic millisecond pulsar binaries using MESA: New constraints from pulsar spin and mass evolution
Devina Misra, Manuel Linares, Claire S. Ye
Compact binary millisecond pulsars (MSPs) with orbital periods d are key to understanding binary evolution involving massive neutron stars (NSs). Due to the ablation of…
A GTC spectroscopic study of three spider pulsar companions: line-based temperatures, a new face-on redback, and improved mass constraints
Jordan A. Simpson, Manuel Linares, Jorge Casares +3
We present GTC-OSIRIS phase-resolved optical spectroscopy of three compact binary MSPs, or 'spiders': PSR J1048+2339, PSR J1810+1744, and (for the first time) PSR J1908+2105. For t…
