A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs
Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72
We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-re…

Dynamical mass of the Serpens intermediate-mass young stellar system EC\,95 with DYNAMO--VLBA
JazmÃn Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +8
We present dynamical mass measurements, obtained from multi-epoch Very Long Baseline Interferometry (VLBI) observations, for the young multiple stellar system EC\,95, located in th…

VLBA Detections in the Oph-S1 Binary System near Periastron Confirmation of its Orbital Elements and Mass
JazmÃn Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +7
Oph-S1 is the most luminous and massive stellar member of the nearby Ophiuchus star-forming region. Previous Very Long Baseline Array (VLBA) observations have shown it to be an int…
