Sulphur monoxide exposes a potential molecular disk wind from the planet-hosting disk around HD100546
Alice Booth, Catherine Walsh, Mihkel Kama +3
Sulphur-bearing volatiles are observed to be significantly depleted in interstellar and circumstellar regions. This missing sulphur is postulated to be mostly locked up in refracto…
The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
Efficiency of radial transport of ices in protoplanetary disks probed with infrared observations: the case of CO
Arthur D. Bosman, Alexander G. G. M. Tielens, Ewine F. van Dishoeck
The efficiency of radial transport of icy solid material from outer disk to the inner disk is currently unconstrained. Efficient radial transport of icy dust grains could significa…
Interpreting Brightness Asymmetries in Transition Disks: Vortex at Dead Zone or Planet Carved Gap Edges?
Zs. Regaly, A. Juhasz, D. Nehez
Recent sub-millimeter observations show non-axisymmetric brightness distributions with a horseshoe-like morphology for more than a dozen transition disks. The most accepted explana…
Possible detection of a bimodal cloud distribution in the atmosphere of HAT-P-32\,A\,b from multi-band photometry
Jeremy Tregloan-Reed, John Southworth, L. Mancini +6
We present high-precision photometry of eight separate transit events in the HAT-P-32 planetary system. One transit event was observed simultaneously by two telescopes of which one…
The occurrence of planets and other substellar bodies around white dwarfs using K2
Lennart van Sluijs, Vincent Van Eylen
The majority of stars both host planetary systems and evolve into a white dwarf (WD). To understand their post-main-sequence (PMS) planetary system evolution, we present a search f…
The signatures of the parental cluster on field planetary systems
Maxwell Xu Cai, Simon Portegies Zwart, Arjen van Elteren
Due to the high stellar densities in young clusters, planetary systems formed in these environments are likely to have experienced perturbations from encounters with other stars. W…
Searching for reflected light from Bootis b with high-resolution ground-based spectroscopy: Approaching the contrast barrier
H. J. Hoeijmakers, I. A. G. Snellen, S. E. van Terwisga
It is challenging to measure the starlight reflected from exoplanets because of the extreme contrast with their host stars. For hot Jupiters, this contrast is in the range of $10^{…
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
O. Vaduvescu, L. Hudin, T. Mocnik +80
One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
A better characterization of the chemical composition of exoplanets atmospheres with ARIEL
Olivia Venot, Benjamin Drummond, Yamila Miguel +3
Since the discovery of the first extrasolar planet more than twenty years ago, we have discovered nearly four thousand planets orbiting stars other than the Sun. Current observatio…
The origin of interstellar asteroidal objects like 1I/2017 U1 'Oumuamua
Simon Portegies Zwart, Santiago Torres, Inti Pelupessy +2
We study the origin of the interstellar object 1I/2017 U1 'Oumuamua by juxtaposing estimates based on the observations with simulations. We speculate that objects like 'Oumuamua ar…
K2-141 b: A 5-M super-Earth transiting a K7 V star every 6.7 hours
O. Barragán, D. Gandolfi, F. Dai +32
We report on the discovery of K2-141 b (EPIC 246393474 b), an ultra-short-period super-Earth on a 6.7-hour orbit transiting an active K7 V star based on data from K2 campaign 12. W…
Three Small Super-Earths Transiting the nearby star GJ 9827
Prajwal Niraula, Seth Redfield, Fei Dai +25
We report on the discovery of three transiting planets around GJ~9827. The planets have radii of 1.75, 1.36, and 2.10~…
DZ Cha: a bona fide photoevaporating disc
H. Canovas, B. Montesinos, M. R. Schreiber +14
DZ Cha is a weak-lined T Tauri star (WTTS) surrounded by a bright protoplanetary disc with evidence of inner disc clearing. Its narrow $\Ha$ line and infrared spectral energy distr…
The circumstellar disk HD169142: gas, dust and planets acting in concert?
A. Pohl, M. Benisty, P. Pinilla +33
HD169142 is an excellent target to investigate signs of planet-disk interaction due to the previous evidence of gap structures. We performed J-band (~1.2μm) polarized intensity…
Capture of exocomets and the erosion of the Oort cloud due to stellar encounters in the Galaxy
Joris Hanse, Lucie Jilkova, Simon F. Portegies Zwart +1
The Oort cloud (OC) probably formed more than 4Gyr ago and has been moving with the Sun in the Galaxy since, exposed to external influences, most prominently to the Galactic ti…
Combining angular differential imaging and accurate polarimetry with SPHERE/IRDIS to characterize young giant exoplanets
Rob G. van Holstein, Frans Snik, Julien H. Girard +11
Young giant exoplanets emit infrared radiation that can be linearly polarized up to several percent. This linear polarization can trace: 1) the presence of atmospheric cloud and ha…
Variable dynamics in the inner disk of HD 135344B revealed with multi-epoch scattered light imaging
Tomas Stolker, Mike Sitko, Bernard Lazareff +12
We present multi-epoch VLT/SPHERE observations of the protoplanetary disk around HD 135344B (SAO 206462). The -band scattered light imagery reveal, with high spatial resolution…
Methanol formation in TW Hya and future prospects for detecting larger complex molecules in disks with ALMA
Catherine Walsh, Shreyas Vissapragada, Harry McGee
Gas-phase methanol was recently detected in a protoplanetary disk for the first time with ALMA. The peak abundance and distribution of methanol observed in TW Hya differed from tha…
