Ephemeris Refinement of the Exoplanet Candidate around the White Dwarf WD1856+534
Abstract
The exoplanet candidate around the white dwarf WD 1856+534 is of special interest for exoplanet atmosphere characterization because of its very cool temperature and potentially large spectral signal in transmission spectroscopy. Here we present ground-based transit follow-up to verify the transit depth and refine the orbital ephemeris allowing for a more accurate scheduling of future transit observations. Our new ephemeris provides transit time predictions with an uncertainty of less than 30 s until the year 2030.
