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…

The Dustiest Galactic S Stars: Mid-Infrared Spectra from SOFIA/FORCAST
Kathleen E. Kraemer, G. C. Sloan, Ramses M. Ramirez
We present spectra of 12 of the reddest, and hence dustiest, S stars in the Milky Way, observed with the FORCAST grisms on SOFIA. S stars are asymptotic giant branch (AGB) stars wi…
