A Kinematic History of Stellar Encounters with Beta Pictoris
Jose Luis Gragera-Más, Santiago Torres, Alexander James Mustill +1
Beta Pictoris is an A-type star hosting a complex planetary system with two massive gas giants and a prominent debris disk. Variable absorption lines in its stellar spectrum have b…
Two intermediate-mass transiting brown dwarfs from the TESS mission
Theron W. Carmichael, Samuel N. Quinn, Alexander J. Mustill +28
We report the discovery of two intermediate-mass brown dwarfs (BDs), TOI-569b and TOI-1406b, from NASA's Transiting Exoplanet Survey Satellite mission. TOI-569b has an orbital peri…
Super-Earth ingestion can explain the anomalously high metal abundances of M67 Y2235
Ross P. Church, Alexander J. Mustill, Fan Liu
We investigate the hypothesis that ingestion of a terrestrial or super-Earth planet could cause the anomalously high metal abundances seen in a turn-off star in the open cluster M6…
Fast spectrophotometry of WD 1145+017
P. Izquierdo, P. Rodríguez-Gil, B. T. Gänsicke +16
WD 1145+017 is currently the only white dwarf known to exhibit periodic transits of planetary debris as well as absorption lines from circumstellar gas. We present the first simult…
20 years of photometric microlensing events predicted by Gaia DR2: Potential planet-hosting lenses within 100 pc
Alexander J Mustill, Melvyn B Davies, Lennart Lindegren
Context. Gaia DR2 offers unparalleled precision on stars' parallaxes and proper motions. This allows the prediction of microlensing events for which the lens stars (and any planets…
Detailed chemical compositions of the wide binary HD 80606/80607: revised stellar properties and constraints on planet formation
F. Liu, D. Yong, M. Asplund +5
Differences in the elemental abundances of planet hosting stars in binary systems can give important clues and constraints about planet formation and evolution. In this study we pe…
