Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
We report the direct imaging discovery of a third exoplanet in the Pictoris system. We detect Pictoris d ( Pic d) in non-coronagraphic observations obtained with VLT/ERI…
The Solirad (So) as a Convenient Unit for Quoting Astronomical Irradiances for Planetary Insolations and Exoplanetary Instellations
Eric E. Mamajek, Jason T. Wright, Noah W. Tuchow +3
Measurements of physical parameters for stars and (exo)planets are often quoted in units normalized to the Sun and/or Earth. The nominal total solar irradiance, ${S}^{\rm N}_{\odot…
A planetary-mass candidate imaged in the Young Suns Exoplanet Survey
Pengyu Liu, Matthew A. Kenworthy, Beth A. Biller +26
Directly imaged exoplanets in wide orbits challenge current gas giant formation theories. They need to form quickly and acquire enough material before the disk dissipates, which ca…
Direct detectability of tidally heated exomoons by photometric orbital modulation
E. Kleisioti, D. Dirkx, X. Tan +1
(Aims) We investigate whether volcanic exomoons can be detected in thermal wavelength light curves due to their phase variability along their orbit. The method we use is based on t…
The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet-planet scattering
Alexander J. Mustill, Melvyn B. Davies, Matthew A. Kenworthy
Several stars show deep transits consistent with discs of roughly 1 Solar radius seen at moderate inclinations, likely surrounding planets on eccentric orbits. We show that this co…
Polarimetric differential imaging with VLT/NACO. A comprehensive PDI pipeline for NACO data (PIPPIN)
S. de Regt, C. Ginski, M. A. Kenworthy +9
The observed diversity of exoplanets can possibly be traced back to the planet formation processes. Planet-disk interactions induce sub-structures in the circumstellar disk that ca…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b
Simon Petrus, Niall Whiteford, Polychronis Patapis +119
The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) com…
A Near-infrared Variability Survey of Young Planetary-mass Objects
Pengyu Liu, Beth A. Biller, Johanna M. Vos +12
We present a photometric variability survey of young planetary-mass objects using the New Technology Telescope in the Js and Ks bands. Surface gravity plays an important role in th…
The Young Suns Exoplanet Survey: Detection of a wide orbit planetary mass companion to a solar-type Sco-Cen member
A. J. Bohn, M. A. Kenworthy, C. Ginski +9
The Young Suns Exoplanet Survey (YSES) consists of a homogeneous sample of 70 young, solar-mass stars located in the Lower Centaurus-Crux subgroup of the Scorpius-Centaurus associa…
First direct detection of a polarized companion outside of a resolved circumbinary disk around CS Cha
C. Ginski, M. Benisty, R. G. van Holstein +18
In the present study we aim to investigate the circumstellar environment of the spectroscopic binary T Tauri star CS Cha. From unresolved mid- to far-infrared photometry it is pred…
Direct detection of scattered light gaps in the transitional disk around HD 97048 with VLT/SPHERE
C. Ginski, T. Stolker, P. Pinilla +28
We studied the well known circumstellar disk around the Herbig Ae/Be star HD 97048 with high angular resolution to reveal undetected structures in the disk, which may be indicative…
Searching for gas giant planets on Solar System scales - A NACO/APP L'-band survey of A- and F-type Main Sequence stars
T. Meshkat, M. A. Kenworthy, M. Reggiani +3
We report the results of a direct imaging survey of A- and F-type main sequence stars searching for giant planets. A/F stars are often the targets of surveys, as they are thought t…
Discovery of a Low-Mass Companion to the F7V star HD 984
T. Meshkat, M. Bonnefoy, E. E. Mamajek +8
We report the discovery of a low-mass companion to the nearby (d = 47 pc) F7V star HD 984. The companion is detected 0.19" away from its host star in the L' band with the Apodizing…
Further Evidence of the Planetary Nature of HD 95086 b from Gemini/NICI H-band Data
T. Meshkat, V. Bailey, J. Rameau +8
We present our analysis of the Gemini/NICI H-band data of HD 95086, following the discovery of the planet HD 95086 b in L'. The H-band data reach a contrast of 12.7 mag relative to…
Evidence for the disintegration of KIC 12557548 b
M. Brogi, C. U. Keller, M. de Juan Ovelar +4
Context. The Kepler object KIC 12557548 b is peculiar. It exhibits transit-like features every 15.7 hours that vary in depth between 0.2% and 1.2%. Rappaport et al. (2012) explain…
