A TESS Detection of Candidate Double White Dwarf Binary with a 3.54 days Period.

GARZA NAVARRO N. and WILSON D.J.

Abstract (from CDS):

We report the recharacterization of TIC 471013547 as an eclipsing white dwarf binary using data obtained with the Transiting Exoplanet Survey Satellite (TESS). Eclipses from both components are detected, and we find a period of 3.541056 ± 0.000185 days with an ephemeris of TJD = 2458441.434 ± 0.000209 days. Its shared features with other double white dwarf eclipsing binaries and its lack of infrared excess indicate that the system likely consists of two white dwarfs.
