Bright Opportunities for Atmospheric Characterization of Small Planets: Masses and Radii of K2-3 b, c, d and GJ3470 b from Radial Velocity Measurements and Spitzer Transits
Molly R. Kosiarek, Ian J. M. Crossfield, Kevin K. Hardegree-Ullman +36
We report improved masses, radii, and densities for four planets in two bright M-dwarf systems, K2-3 and GJ3470, derived from a combination of new radial velocity and transit obser…
Revisiting the HIP41378 system with K2 and Spitzer
David Berardo, Ian J. M. Crossfield, Michael Werner +12
We present new observations of the multi-planet system HIP~41378, a bright star ( = 8.9, = 7.7) with five known transiting planets. Observations in Campaign 5 of the K2 mi…
High-contrast imaging of tight resolved binaries with two vector vortex coronagraphs in cascade with the Palomar SDC instrument
Jonas Kuhn, Sebastian Daemgen, Ji Wang +6
More than half of the stars in the solar neighborhood reside in binary/multiple stellar systems, and recent studies suggest that gas giant planets may be more abundant around binar…
The TRENDS High-Contrast Imaging Survey. VII. Discovery of a Nearby Sirius-like White Dwarf System (HD 169889)
Justin R. Crepp, Erica J. Gonzales, Brendan P. Bowler +8
Monitoring the long-term radial velocity (RV) and acceleration of nearby stars has proven an effective method for directly detecting binary and substellar companions. Some fraction…
Constraining the presence of giant planets in two-belt debris disk systems with VLT/SPHERE direct imaging and dynamical arguments
Elisabeth Matthews, Sasha Hinkley, Arthur Vigan +10
Giant, wide-separation planets often lie in the gap between multiple, distinct rings of circumstellar debris: this is the case for the HR\,8799 and HD\,95086 systems, and even the…
Planetary Candidates from K2 Campaign 16
Liang Yu, Ian J. M. Crossfield, Joshua E. Schlieder +20
Given that Campaign 16 of the K2 mission is one of just two K2 campaigns observed so far in "forward-facing" mode, which enables immediate follow-up observations from the ground, w…
HD 104860 and HD 192758: two debris disks newly imaged in scattered-light with HST
É. Choquet, G. Bryden, M. D. Perrin +15
We present the first scattered-light images of two debris disks around the F8 star HD 104860 and the F0V star HD 192758, respectively and pc away. We detected the…
An Improved Transit Measurement for a 2.4 R_{Earth} Planet Orbiting A Bright Mid-M Dwarf K228
Ge Chen, Heather A. Knutson, Courtney D. Dressing +13
We present a new {\em Spitzer} transit observation of K228b, a sub-Neptune () orbiting a relatively bright (, $K_{\rm mag…
