Detection and characterization of an ultra-dense sub-Neptune planet orbiting the Sun-like star HD 119130
R. Luque, G. Nowak, E. Pallé +51
We present the discovery and characterization of a new transiting planet from Campaign 17 of the Kepler extended mission K2. HD 119130 b is a warm sub-Neptune on a 17-d orbit aroun…
The effect of carbon grain destruction on the chemical structure of protoplanetary disks
Chen-En Wei, Hideko Nomura, Jeong-Eun Lee +3
The bulk composition of the Earth is dramatically carbon poor compared to that of the interstellar medium, and this phenomenon extends to the asteroid belt. To interpret this carbo…
Gas density perturbations induced by forming planet(s) in the AS 209 protoplanetary disk as seen with ALMA
Cécile Favre, Davide Fedele, Luke Maud +6
The formation of planets occurs within protoplanetary disks surrounding young stars, resulting in perturbation of the gas and dust surface densities. Here, we report the first evid…
Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b
Lisa Nortmann, Enric Pallé, Michael Salz +25
Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, affecting their physical and chemical evolution. Studies of atmospheric escape from ex…
Detection of He I Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy
M. Salz, S. Czesla, P. C. Schneider +35
We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near-infra…
Spectrally resolved helium absorption from the extended atmosphere of a warm Neptune-mass exoplanet
R. Allart, V. Bourrier, C. Lovis +7
Stellar heating causes atmospheres of close-in exoplanets to expand and escape. These extended atmospheres are difficult to observe because their main spectral signature - neutral…
A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE
G. Cugno, S. P. Quanz, S. Hunziker +37
Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…
HD219666b: A hot-Neptune from TESS Sector 1
M. Esposito, D. J. Armstrong, D. Gandolfi +73
We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (Mstar = 0.92 +/- 0.03 MSun, Rstar = 1.03 +/- 0.03…
The Little Dippers: Transits of Star-grazing Exocomets?
Megan Ansdell, Eric Gaidos, Tom L. Jacobs +9
We describe EPIC 205718330 and EPIC 235240266, two systems identified in the K2 data whose light curves contain episodic drops in brightness with shapes and durations similar to th…
Catching a planet: A tidal capture origin for the exomoon candidate Kepler 1625b I
Adrian S. Hamers, Simon F. Portegies Zwart
The (yet-to-be confirmed) discovery of a Neptune-sized moon around the ~3.2 Jupiter-mass planet in Kepler 1625 puts interesting constraints on the formation of the system. In parti…
Multiple water band detections in the CARMENES near-infrared transmission spectrum of HD 189733 b
F. J. Alonso-Floriano, A. Sánchez-López, I. A. G. Snellen +27
Aims: We explore the capabilities of CARMENES for characterizing hot-Jupiter atmospheres by targeting multiple water bands, in particular, those at 1.15 and 1.4 m. Hubble Space…
Variable Outer Disk Shadowing Around the Dipper Star RX J1604.3-2130
P. Pinilla, M. Benisty, J. de Boer +6
Low brightness dips have been recently observed in images of protoplanetary disks, and they are believed to be shadows by the inner disk. We present VLT/SPHERE polarimetric differe…
The Ring Structure in the MWC 480 Disk Revealed by ALMA
Yao Liu, Giovanni Dipierro, Enrico Ragusa +20
Gap-like structures in protoplanetary disks are likely related to planet formation processes. In this paper, we present and analyze high resolution (0.17*0.11 arcsec) 1.3 mm ALMA c…
WASP-166b: a bloated super-Neptune transiting a V = 9 star
Coel Hellier, D. R. Anderson, A. H. M. J. Triaud +21
We report the discovery of WASP-166b, a super-Neptune planet with a mass of 0.1 Mjup (1.9 Mnep) and a bloated radius of 0.63 Rjup. It transits a V = 9.36, F9V star in a 5.44-d orbi…
PynPoint: a modular pipeline architecture for processing and analysis of high-contrast imaging data
Tomas Stolker, Markus J. Bonse, Sascha P. Quanz +4
The direct detection and characterization of planetary and substellar companions at small angular separations is a rapidly advancing field. Dedicated high-contrast imaging instrume…
The Formation of Solar System Analogs in Young Star Clusters
Simon Portegies Zwart
The Solar system was once rich in the short-lived radionuclide (SLR) Al\, but deprived in Fe. Several models have been proposed to explain these anomalous abundances…
Observability of molecular species in a nitrogen dominated atmosphere for 55 Cancri e
Yamila Miguel
One of the key goals of exoplanet science is the atmospheric characterisation of super-Earths. Atmospheric abundances provide insight on the formation and evolution of those planet…
Constraining the period of the ringed secondary companion to the young star J1407 with photographic plates
R. T. Mentel, M. A. Kenworthy, D. A. Cameron +13
Context. The 16 Myr old star 1SWASP J140747.93-394542.6 (V1400 Cen) underwent a series of complex eclipses in May 2007, interpreted as the transit of a giant Hill sphere filling de…
