The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk
Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35
We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) XI: Gas-dust interactions and radial offsets between micron and millimetre-sized grains
J. Olofsson, M. R. Jankovic, S. Marino +22
The dust observed in debris disks is the result of a collisional cascade initiated from km-sized parent bodies. Using near-infrared to sub-millimeter observations, we can pr…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) V: Comparison between scattered light and thermal emission
J. Milli, J. Olofsson, M. Bonduelle +33
Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved at high angular resolution at…
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) VII: Optically thick gas with broad CO gaussian local line profiles in the HD 121617 disc
A. Brennan, L. Matrà, S. Mac Manamon +24
CO gas has been detected in 20 debris discs. We present ALMA observations of the CO-rich HD 121617 debris disc from the ARKS survey. Using high-resolution Band 7 observations…
A radially broad collisional cascade in the debris disk of Ophiuchi observed by JWST
Yinuo Han, Mark Wyatt, Kate Y. L. Su +13
The A1V star Oph, at a distance of 29.7 pc, is known from Spitzer imaging to host a debris disk with a large radial extent and from its spectral energy distribution to host inn…
Sudden extreme obscuration of a Sun-like main-sequence star: evolution of the circumstellar dust around ASASSN-21qj
Jonathan P. Marshall, Steve Ertel, Francisca Kemper +6
ASASSN-21qj is a distant Sun-like star that recently began an episode of deep dimming events after no prior recorded variability. Here we examine archival and newly obtained optica…
The GAPS program at TNG XLVII: The unusual formation history of V1298 Tau
D. Turrini, F. Marzari, D. Polychroni +33
Observational data from space and ground-based campaigns reveal that the 10-30 Ma old V1298 Tau star hosts a compact and massive system of four planets. Mass estimates for the two…
Stirred but not shaken: a multi-wavelength view of HD 16743's debris disc
Jonathan P. Marshall, Julien Milli, Elodie Choquet +6
Planetesimals -- asteroids and comets -- are the building blocks of planets in protoplanetary discs and the source of dust, ice and gas in debris discs. Along with planets they com…
The high-albedo, low polarization disk around HD 114082 harbouring a Jupiter-sized transiting planet
N. Engler, J. Milli, R. Gratton +36
We present new optical and near-IR images of debris disk around the F-type star HD 114082. We obtained direct imaging observations and analysed the TESS photometric time series dat…
The SHARDDS survey: limits on planet occurrence rates based on point sources analysis via the Auto-RSM framework
C. -H. Dahlqvist, J. Milli, O. Absil +7
In the past decade, HCI surveys provided new insights about the frequency and properties of substellar companions at separation larger than 5 au. In this context, our study aims to…
HORuS transmission spectroscopy and revised planetary parameters of KELT-7b
H. M. Tabernero, M. R. Zapatero Osorio, C. Allende Prieto +7
We report on the high-resolution spectroscopic observations of two planetary transits of the hot Jupiter KELT-7b ( 1.28 0.17 M, 20…
Rapid contraction of giant planets orbiting the 20 million-years old star V1298 Tau
A. Suárez Mascareño, M. Damasso, N. Lodieu +41
Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about…
The REASONS Survey: Resolved Millimeter Observations of a Large Debris Disk Around the Nearby F Star HD 170773
Aldo G. Sepulveda, Luca Matra, Grant M. Kennedy +15
Debris disks are extrasolar analogs to our own Kuiper Belt and they are detected around at least 17% of nearby Sun-like stars. The morphology and dynamics of a disk encode informat…
Polarization measurements of hot dust stars and the local interstellar medium
J. P. Marshall, D. V. Cotton, K. Bott +7
Debris discs are typically revealed through excess emission at infrared wavelengths. Most discs exhibit excess at mid- and far-infrared wavelengths, analogous to the solar system's…
The first planet detected in the WTS: an inflated hot-Jupiter in a 3.35 day orbit around a late F-star [ERRATUM]
M. Cappetta, R. P. Saglia, J. L. Birkby +35
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope (UKIRT) in…
WTS-2 b: a hot Jupiter orbiting near its tidal destruction radius around a K-dwarf
J. L. Birkby, M. Cappetta, P. Cruz +34
We report the discovery of WTS-2 b, an unusually close-in 1.02-day hot Jupiter (Mp=1.12MJ, Rp=1.363RJ) orbiting a K2V star, which has a possible gravitationally-bound M-dwarf compa…
Can eccentric debris disks be long-lived? A first numerical investigation and application to Reticuli
V. Faramaz, H. Beust, P. Thébault +13
Imaging of debris disks has found evidence for both eccentric and offset disks. One hypothesis is that these provide evidence for massive perturbers that sculpt the observed struct…
Searching for transits in the WTS with difference imaging light curves
Jesus Zendejas, Johannes Koppenhoefer, Roberto P. Saglia +13
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses ape…

A. V. Krivov, C. Eiroa, T. Löhne +24
(abridged) Infrared excesses associated with debris disk host stars detected so far peak at wavelengths around ~100μm or shorter. However, six out of 31 excess sources in the Hersc…
