The Gliese 86 Binary System: A Warm Jupiter Formed in a Disk Truncated at ≈2 au
Zeng, Yunlin; Brandt, Timothy D.; Li, Gongjie; Dupuy, Trent J.; Li, Yiting; Brandt, G. Mirek; Farihi, Jay; Horner, Jonathan; Wittenmyer, Robert A.; Butler, R. Paul.; Tinney, Christopher G.; Carter, Bradley D.; Wright, Duncan J.; Jones, Hugh R. A.; O’Toole, Simon J. (2022-10-12)Gliese 86 is a nearby K dwarf hosting a giant planet on a ≈16 day orbit and an outer white dwarf companion on a ≈century-long orbit. In this study we combine radial velocity data (including new measurements spanning more ... -
High-Precision Radio and Infrared Astrometry of LSPM J1314+1320AB - I : Parallax, Proper Motions, and Limits on Planets
Forbrich, Jan; Dupuy, Trent J.; Reid, Mark J.; Berger, Edo; Rizzuto, Aaron; Mann, Andrew W.; Liu, Michael C.; Aller, Kimberly; Kraus, Adam L. (2016-08-03)We present multi-epoch astrometric radio observations with the Very Long Baseline Array (VLBA) of the young ultracool-dwarf binary LSPM J1314+1320AB . The radio emission comes from the secondary star. Combining the VLBA ... -
High-Precision Radio and Infrared Astrometry of LSPM J1314+1320AB - II: Testing Pre--Main-Sequence Models at the Lithium Depletion Boundary with Dynamical Masses
Dupuy, Trent J.; Forbrich, Jan; Rizzuto, Aaron; Mann, Andrew W.; Aller, Kimberly; Liu, Michael C.; Kraus, Adam L.; Berger, Edo (2016-08-03)We present novel tests of pre$-$main-sequence models based on individual dynamical masses for the M7 binary LSPM J1314+1320AB. Joint analysis of our Keck adaptive optics astrometric monitoring along with Very Long Baseline ... -
On the binary frequency of the lowest mass members of the pleiades with hubble space telescope wide field camera 3
Garcia, E. V.; Dupuy, Trent J.; Allers, Katelyn N.; Liu, Michael C.; Deacon, Niall R. (2015-05-01)We present the results of a Hubble Space Telescope Wide Field Camera 3 (WFC3) imaging survey of 11 of the lowest mass brown dwarfs in the Pleiades known (25-40 MJup). These objects represent the predecessors to T dwarfs ...
