Isochronal age-mass discrepancy of young stars: SCExAO/CHARIS integral field spectroscopy of the HIP 79124 triple system
Ruben Asensio-Torres, Thayne Currie, Markus Janson +24
We present SCExAO/CHARIS 1.1--2.4 micron integral field direct spectroscopy of the young HIP 79124 triple system. HIP 79124 is a member of the Scorpius-Centaurus association, consi…
SOFIA/FORCAST resolves 30 - 40 um extended dust emission in nearby active galactic nuclei
Lindsay Fuller, Enrique Lopez-Rodriguez, Chris Packham +7
We present arcsecond-scale observations of the active galactic nuclei (AGNs) of seven nearby Seyfert galaxies observed from the Stratospheric Observatory For Infrared Astronomy (SO…
The upGREAT dual frequency heterodyne arrays for SOFIA
C. Risacher, R. Güsten, J. Stutzk +30
We present the performance of the upGREAT heterodyne array receivers on the SOFIA telescope after several years of operations. This instrument is a multi-pixel high resolution (R >…
SOFIA Far Infrared Imaging Polarimetry of M82 and NGC 253: Exploring the Super-Galactic Wind
Terry Jay Jones, C. Darren Dowell, Enrique Lopez Rodriguez +22
We present Far-Infrared polarimetry observations of M82 at 53 and and NGC 253 at , which were taken with HAWC+ in polarimetry mode on the Stratospheric Ob…
Observations of Binary Stars with the Differential Speckle Survey Instrument. VIII. Measures of Metal-Poor Stars and Triple Stars from 2015 to 2018
Elliott P. Horch, Andrei Tokovinin, Samuel A. Weiss +15
We present 248 speckle observations of 43 binary and 19 trinary star systems chosen to make progress in two main areas of investigation: the fundamental properties of metal poor st…
Hubble PanCET: An extended upper atmosphere of neutral hydrogen around the warm Neptune GJ 3470 b
V. Bourrier, A. Lecavelier des Etangs, D. Ehrenreich +16
GJ 3470b is a warm Neptune transiting an M-dwarf star at the edge of the evaporation desert. It offers the possibility of investigating how low-mass, close-in exoplanets evolve und…
