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 ...
