Confirming new white dwarf-ultracool dwarf binary candidates
Miriam Hogg, Sarah Casewell, Graham Wynn +8
We present the results of a study to discover prospective new white dwarf-L dwarf binaries as identified by their near-infrared excesses in the UKIDSS catalogue. We obtained optica…
NGTS-10b: The shortest period hot Jupiter yet discovered
James McCormac, Edward Gillen, James A. G. Jackman +44
We report the discovery of a new ultra-short period transiting hot Jupiter from the Next Generation Transit Survey (NGTS). NGTS-10b has a mass and radius of $2.162\,^{+0.092}_{-0.1…
Signs of accretion in the white dwarf + brown dwarf binary NLTT5306
E. S. Longstaff, S. L. Casewell, G. A. Wynn +4
We present new XSHOOTER spectra of NLTT5306, a 0.44 0.04\msun white dwarf in a short period (101\,min) binary system with a brown dwarf companion that is likely to have previ…
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=…
Emission lines in the atmosphere of the irradiated brown dwarf WD0137-349B
E. S. Longstaff, S. L. Casewell, G. A. Wynn +2
We present new optical and near-infrared spectra of WD0137-349; a close white dwarf - brown dwarf non-interacting binary system with a period of 114 minutes. We have confi…
