NLTT5306B: an inflated, weakly irradiated brown dwarf
S. L. Casewell, J. Debes, I. P. Braker +4
We present Spitzer observations at 3.6 and 4.5 microns and a near-infrared IRTF SpeX spectrum of the irradiated brown dwarf NLTT5306B. We determine that the brown dwarf has a spect…
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…
WD1032+011, an inflated brown dwarf in an old eclipsing binary with a white dwarf
S. L. Casewell, C. Belardi, S. G. Parsons +11
We present the discovery of only the third brown dwarf known to eclipse a non-accreting white dwarf. Gaia parallax information and multi-colour photometry confirm that the white dw…
