This fast and energetic (\dot{E}=3x10^35^erg/s) millisecond pulsar was first detected as a gamma-ray point source in Fermi Large Area Telescope (LAT) sky survey observations. Guided by a steep-spectrum radio point source in the Fermi error region, we performed a search at 820MHz with the Green Bank Telescope that first discovered the pulsations. The initial radio pulse timing observations provided enough information to seed a search for gamma-ray pulsations in the LAT data, from which we derive a timing solution valid for the full Fermi mission. In addition to the discovery and timing of radio and gamma-ray pulsations, we searched for X-ray pulsations using NICER but no significant pulsations were detected. We also obtained time-series r-band photometry that indicates strong heating of the companion star by the pulsar wind. Material blown off the heated companion eclipses the 820MHz radio pulse during inferior conjunction of the companion for ~10% of the orbit, which is twice the angle subtended by its Roche lobe in an edge-on system.2022ApJ...927..216Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/927/216CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/psr : ATNF Pulsar Catalogue (Manchester+, 2005)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/ApJS/208/17 : 2nd Fermi LAT cat. of gamma-ray pulsars (2PC) (Abdo+, 2013)J/ApJ/769/108 : Optical photometry of 4 millisecond pulsars (Breton+, 2013)J/ApJ/810/85 : Obs. of first Fermi-LAT sources at Parkes (Camilo+, 2015)J/ApJ/814/128 : Timing noise & astrometry of Fermi-LAT pulsars (Kerr+, 2015)J/A+A/598/A78 : The GMRT 150MHz all-sky radio survey (Intema+, 2017)J/ApJ/872/42 : Opt. sp. of redback ms pulsar binaries (Strader+, 2019)J/ApJS/247/33 : The Fermi LAT fourth source catalog (4FGL) (Abdollahi+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/927/216https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/927/216http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/927/216https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/927/216https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/927/216http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/927/216GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapGamma-rayOpticalInfraredRadiodefaultJ/ApJ/927/216/fig5MDM 2.4m r-band light curve of PSR J1555-2908recnoRecord number assigned by the VizieR team.
