Characterization of Planetary Systems with Astrometry
Gisela N. Ortiz-Leon
Astrometry is the oldest method used to search for extrasolar planets. This technique provides key information about a planetary system, like the true mass of planets and its three…
Upper Limits to the Proper Motions of JuMBO 24, a Jupiter-Mass Binary Object Candidate in Orion
Luis F. Rodriguez, Laurent Loinard, Luis Zapata +1
Using JWST near-infrared data of the inner Orion Nebula, \citet{Pearson_McCaughrean_2023} detected 40 binary systems they proposed to be Jupiter-Mass Binary Objects (JuMBOs) -- alt…
3D orbital architecture of a dwarf binary system and its planetary companion
Salvador Curiel, Gisela N. Ortiz-León, Amy J. Mioduszewski +2
Because of the diversity of stellar masses and orbital sizes of binary systems, and the complex interaction between star-star, star-planet and planet-planet, it has been difficult…
An astrometric planetary companion candidate to the M9 Dwarf TVLM 513-46546
Salvador Curiel, Gisela N. Ortiz-León, Amy J. Mioduszewski +1
Astrometric observations of the M9 dwarf TVLM 51346546 taken with the VLBA reveal an astrometric signature consistent with a period of 221 5 days. The orbital fit implies…
