The Pandora SmallSat: post-launch operations and mission update
Trevor O. Foote, Elisa V. Quintana, Jessie L. Dotson +41
The Pandora SmallSat is a NASA flight project designed to study the atmospheres of exoplanets. Transmission spectroscopy of transiting exoplanets provides our best opportunity to i…
Disk-Star Alignment I: Pre-Main-Sequence Stellar Parameters and the Statistical Alignment Between Disks and Stellar Rotation
Matthew J. Fields, Andrew W. Mann, Aurora Kesseli +1
Astronomers generally assume planet-forming disks are aligned with the rotation of their host star. However, recent observations have shown evidence of warping in protoplanetary di…
The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
Retrieval survey of metals in six ultra-hot Jupiters: Trends in chemistry, rain-out, ionisation and atmospheric dynamics
Siddharth Gandhi, Aurora Kesseli, Yapeng Zhang +9
Ground-based high-resolution spectroscopy (HRS) has detected numerous chemical species and atmospheric dynamics in exoplanets, most notably ultra-hot Jupiters (UHJs). However, quan…
Contemporaneous Observations of Luminosities and Photometric Amplitudes for M Dwarfs
Aylin García Soto, Elisabeth R. Newton, Stephanie T. Douglas +2
While many M dwarfs are known to have strong magnetic fields and high levels of magnetic activity, we are still unsure about the properties of their starspots and the origin of the…
Characterizing the protolunar disk of the accreting companion GQ Lupi B
Tomas Stolker, Sebastiaan Y. Haffert, Aurora Y. Kesseli +11
GQ Lup B is a young and accreting, substellar companion that appears to drive a spiral arm in the circumstellar disk of its host star. We report high-contrast imaging observations…
Classifying Single Stars and Spectroscopic Binaries Using Optical Stellar Templates
Benjamin R. Roulston, Paul G. Green, Aurora Y. Kesseli
Stellar spectral classification is a fundamental tool of modern astronomy, providing insight into physical characteristics such as effective temperature, surface gravity, and metal…
Effective Temperatures of Low-Mass Stars from High-Resolution H-band Spectroscopy
Ricardo López-Valdivia, Gregory N. Mace, Kimberly R. Sokal +9
High-resolution, near-infrared spectra will be the primary tool for finding and characterizing Earth-like planets around low-mass stars. Yet, the properties of exoplanets can not b…
Radii of 88 M Subdwarfs and Updated Radius Relations for Low-Metallicity M Dwarf Stars
Aurora Y. Kesseli, J. Davy Kirkpatrick, Sergio B. Fajardo-Acosta +9
M subdwarfs are low-metallicity M dwarfs that typically inhabit the halo population of the Galaxy. Metallicity controls the opacity of stellar atmospheres; in metal poor stars, hyd…
Magnetic Inflation and Stellar Mass II: On the Radii of Single, Rapidly Rotating, Fully Convective M Dwarf Stars
Aurora Y. Kesseli, Philip S. Muirhead, Andrew W. Mann +1
Main sequence, fully-convective M dwarfs in eclipsing binaries are observed to be larger than stellar evolutionary models predict by as much as . A proposed explanation fo…
An empirical template library of stellar spectra for a wide range of spectral classes, luminosity classes, and metallicities using SDSS BOSS spectra
Aurora Y. Kesseli, Andrew A. West, Mark Veyette +3
We present a library of empirical stellar spectra created using spectra from the Sloan Digital Sky Survey's Baryon Oscillation Spectroscopic Survey (BOSS). The templates cover spec…
A Model for (Quasi-)Periodic Multi-wavelength Photometric Variability in Young Stellar Objects
Aurora Y. Kesseli, Maya A. Petkova, Kenneth Wood +7
We present radiation transfer models of rotating young stellar objects (YSOs) with hotspots in their atmospheres, inner disk warps and other 3-D effects in the nearby circumstellar…
