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 García-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…
COBIPULSE: A Systematic Search for Compact Binary Millisecond Pulsars
Marco Turchetta, Manuel Linares, Karri Koljonen +5
We report here the results obtained from a systematic optical photometric survey aimed at finding new compact binary millisecond pulsars (also known as "spiders"): the COmpact BIna…
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…
The Orbit and Companion of PSR J1622-0315: Variable Asymmetry and a Massive Neutron Star
Bidisha Sen, Manuel Linares, Mark R. Kennedy +6
The companion to PSR J1622-0315, one of the most compact known redback millisecond pulsars, shows extremely low irradiation despite its short orbital period. We model this system t…
The invisible black widow PSR J1720-0534: implications for the electron density towards the North Polar Spur
Karri I. I. Koljonen, Sindre S. Lindseth, Manuel Linares +2
Radio emission from pulsars can be used to map out their distances through dispersion measure (DM), which quantifies the amount of radio pulse dispersion. However, this method reli…
Gamma-ray observations of MAXI J1820+070 during the 2018 outburst
H. Abe, S. Abe, V. A. Acciari +439
MAXI J1820+070 is a low-mass X-ray binary with a black hole as a compact object. This binary underwent an exceptionally bright X-ray outburst from March to October 2018, showing ev…
The binary millisecond pulsar PSR J1023+0038 -- II. Optical spectroscopy
T. Shahbaz, M. Linares, P. Rodriguez-Gil +1
We present time-resolved optical spectroscopy of the `redback' binary millisecond pulsar system PSR J1023+0038 during both its radio pulsar (2009) and accretion disc states (2014 a…
The binary millisecond pulsar PSR J1023+0038 during its accretion state - I. Optical variability
T. Shahbaz, M. Linares, S. P. Nevado +7
We present time-resolved optical photometry of the binary millisecond `redback' pulsar PSR J1023+0038 (=AY Sex) during its low-mass X-ray binary phase. The light curves taken betwe…
X-ray states of redback millisecond pulsars
Manuel Linares
Compact binary millisecond pulsars with main-sequence donors, often referred to as "redbacks", constitute the long-sought link between low-mass X-ray binaries and millisecond radio…
