Multi-wavelength observations of the EUV variable metal-rich white dwarf GD 394
David J. Wilson, Boris T. Gaensicke, Detlev Koester +13
We present new Hubble Space Telescope (HST) ultraviolet and ground-based optical observations of the hot, metal-rich white dwarf GD 394. Extreme-ultraviolet (EUV) observations in 1…
NGTS-4b: A sub-Neptune Transiting in the Desert
Richard G. West, Edward Gillen, Daniel Bayliss +48
We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34d orbit. NGTS-4b has a mass M=M_E and radius R=…
A low-mass eclipsing binary within the fully convective zone from the NGTS
S. L. Casewell, L. Raynard, C. A. Watson +22
We have discovered a new, near-equal mass, eclipsing M dwarf binary from the Next Generation Transit Survey. This system is only one of 3 field age ( 1 Gyr), late M dwarf eclips…
The first sub-70 minute non-interacting WD-BD system: EPIC212235321
S. L. Casewell, I. P. Braker, S. G. Parsons +9
We present the discovery of the shortest-period, non-interacting, white dwarf-brown dwarf post-common-envelope binary known. The K2 light curve shows the system, EPIC 21223532 has…
