Surprise non-detection of Upsilon Andromedae b with MIRC-X and MYSTIC at the CHARA Array

Tyler Gardner, John D. Monnier, Stefan Kraus +11

Ground-based long baseline interferometry is a powerful tool for characterizing exoplanets which are too close to their host star to be imaged with single-dish telescopes. The CHAR…

ACCESS, LRG-BEASTS, & MOPSS: Featureless Optical Transmission Spectra of WASP-25b and WASP-124b

Chima D. McGruder, Mercedes López-Morales, James Kirk +14

We present new optical transmission spectra for two hot Jupiters: WASP-25b (M = 0.56~M; R = 1.23 R; P =~3.76 days) and WASP-124b (M = 0.58~M; R = 1.34 R; P = 3.37 d…

Three-dimensional orbit of AC Her determined: Binary-induced truncation cannot explain the large cavity in this post-AGB transition disk

Narsireddy Anugu, Jacques Kluska, Tyler Gardner +17

Some evolved binaries, namely post-asymptotic giant branch binaries, are surrounded by stable and massive circumbinary disks similar to protoplanetary disks found around young star…

Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary-mass companion

S. Hinkley, S. Lacour, G. -D. Marleau +110

Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner…

A detailed analysis of the Gl 486 planetary system

J. A. Caballero, E. Gonzalez-Alvarez, M. Brady +64

The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3 R_Terra and 3.0 M_Terra that…

EXPRES. III. Revealing the Stellar Activity Radial Velocity Signature of Eridani with Photometry and Interferometry

Rachael M. Roettenbacher, Samuel H. C. Cabot, Debra A. Fischer +20

The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) sh…

Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY

J. J. Wang, A. Vigan, S. Lacour +101

We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 as precision astromet…

The ExoGRAVITY project: using single mode interferometry to characterize exoplanets

S. Lacour, J. J. Wang, M. Nowak +89

Combining adaptive optics and interferometric observations results in a considerable contrast gain compared to single-telescope, extreme AO systems. Taking advantage of this, the E…

Direct confirmation of the radial-velocity planet Pic c

M. Nowak, S. Lacour, A. -M. Lagrange +90

Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…

Spin-orbit alignment of the Pictoris planetary system

Stefan Kraus, Jean-Baptiste LeBouquin, Alexander Kreplin +6

A crucial diagnostic that can tell us about processes involved in the formation and dynamical evolutionof planetary systems is the angle between the rotation axis of a star and a p…

MOPSS II: Extreme Optical Scattering Slope for the Inflated Super-Neptune HATS-8b

E. M. May, T. Gardner, E. Rauscher +1

We present results for the inflated super-Neptune HATS-8b from MOPSS, The Michigan Optical Planetary Spectra Survey. This program is aimed at creating a database of optical planeta…
