A New Methodology for Classifying Eclipsing Binaries with Kepler Data and Deep Learning
Mousam Mondal, Patricia Cruz, Hugh R. A. Jones +2
We present a new method for the automated classification of eclipsing binaries, into contact, detached, and semi-detached types using Kepler data. Phase-folded light curves are gen…
J1250+0455AB an ultracool binary in a hierarchical triple system
Sayan Baig, R. L. Smart, Hugh R. A. Jones +7
We report the discovery of the ultracool dwarf binary system J1250+0455AB, a low-mass (M 0.2 M) system in which the components straddle the M/L dwa…
The Gaia Ultracool Dwarf Sample -- VI. Spectral Types and Properties of 51 Ultracool Dwarfs
Gemma Cheng, H. R. A. Jones, R. L. Smart +7
Near-infrared spectra from the IRTF/SpeX and Blanco/ARCoIRIS telescope/instrument combinations are used for spectroscopic classification, to measure radial velocities and for the i…
The Gaia Ultracool Dwarf Sample -- V: The Ultracool Dwarf Companion catalogue
Sayan Baig, R. L. Smart, Hugh R. A. Jones +4
We present the Ultracool Dwarf Companion Catalogue of 278 multiple systems, 32 of which are newly discovered, each with at least one spectroscopically confirmed Ultracool Dwarf, wi…
Ultracool Spectroscopic Outliers in Gaia DR3
W. J. Cooper, R. L. Smart, H. R. A. Jones +1
Gaia DR3 provided a first release of RP spectra and astrophysical parameters for ultracool dwarfs. We used these Gaia RP spectra and astrophysical parameters to select the most out…
