CHARA/MIRC-X -- a high-sensitive six telescope interferometric imager concept, commissioning, and early science
Narsireddy Anugu, Jean-Baptiste Le Bouquin, John D. Monnier +14
MIRC-X is a six telescope beam combiner at the CHARA array that works in J and H wavelength bands and provides an angular resolution equivalent to a =331m diameter telescope. Th…
The Solar Neighborhood XLVII: Comparing M Dwarf Models with Hubble Space Telescope Dynamical Masses and Spectroscopy
Serge B. Dieterich, Andrew Simler, Todd J. Henry +1
We use HST/STIS optical spectroscopy of ten M dwarfs in five closely separated binary systems to test models of M dwarf structure and evolution. Individual dynamical masses ranging…
A Hypergradient Approach to Robust Regression without Correspondence
Yujia Xie, Yixiu Mao, Simiao Zuo +4
We consider a variant of regression problem, where the correspondence between input and output data is not available. Such shuffled data is commonly observed in many real world pro…
The Volume-Complete Sample of M Dwarfs with Masses 0.1 <= M/M_sol <= 0.3 within 15 Parsecs
Jennifer G. Winters, David Charbonneau, Todd J. Henry +4
M dwarfs with masses 0.1 <= M/M_sol <= 0.3 are under increasing scrutiny because these fully convective stars pose interesting astrophysical questions regarding their magnetic acti…
Space Telescope and Optical Reverberation Mapping Project. XIII. An Atlas of UV and X-ray Spectroscopic Signatures of theDisk Wind in NGC 5548
M. Dehghanian, G. J. Ferland, B. M. Peterson +8
The unusual behavior of the spectral lines of NGC5548 during the STORM campaign demonstrated a missing piece in the structure of AGNs. For a two-month period in the middle of the c…
Gaia Gaps and the Physics of Low-Mass Stars. I. The Fully Convective Boundary
Gregory A. Feiden, Khian Skidmore, Wei-Chun Jao
The Gaia M-dwarf gap is a significant under-density of stars observed near in a color-magnitude diagram for stars within 200 pc of the Sun. It has been proposed that t…
