Optical Follow-Up of Two Spider Pulsar Candidates: An Irradiated Redback and a Possible Double Giant Impostor
Bettina Due, Jundile Bridziute, Manuel Linares +2
Compact binary millisecond pulsars (nicknamed "spiders") are a growing class of neutron stars: more than 100 systems are known in the Galactic field, including more than 30 candida…
Searching for optical pulsations from spider millisecond pulsars with the fast photometer SiFAP2
Christian Malacaria, Alessandro Papitto, Filippo Ambrosino +19
Optical pulsations from millisecond pulsars (MSPs) have recently been discovered from a transitional MSP and an accreting MSP. Evidence for optical pulsations has also been found f…
COBIPLANE: A Systematic Search for Compact Binary Millisecond Pulsars at Low Galactic Latitudes
Marco Turchetta, Manuel Linares, Karri Koljonen +2
We present the main results obtained from the COmpact BInary Pulsar search in the low-LAtitude NEighborhood (COBIPLANE), an optical photometric survey designed to find new `spider'…
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…
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…
