Triton Haze Analogues: the Role of Carbon Monoxide in Haze Formation
Sarah E. Moran, Sarah M. Hörst, Chao He +7
Triton is the largest moon of the Neptune system and possesses a thin nitrogen atmosphere with trace amounts of carbon monoxide and methane, making it of similar composition to tha…
The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
BEBOP III. Observations and an independent mass measurement of Kepler-16 (AB) b -- the first circumbinary planet detected with radial velocities
Amaury H. M. J. Triaud, Matthew R. Standing, Neda Heidari +30
The radial velocity method is amongst the most robust and most established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their rel…
A wide-orbit giant planet in the high-mass b Centauri binary system
Markus Janson, Raffaele Gratton, Laetitia Rodet +24
Planet formation occurs around a wide range of stellar masses and stellar system architectures. An improved understanding of the formation process can be achieved by studying it ac…
Cronomoons: origin, dynamics, and light-curve features of ringed exomoons
Mario Sucerquia, Jaime A. Alvarado-Montes, Amelia Bayo +8
In recent years, technical and theoretical work to detect moons and rings around exoplanets has been attempted. The small mass/size ratios between moons and planets means this is v…
GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star
Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru +75
Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution p…
Probing inner and outer disk misalignments in transition disks
A. J. Bohn, M. Benisty, K. Perraut +16
For several transition disks (TDs), dark regions interpreted as shadows have been observed in scattered light imaging and are hypothesized to originate from misalignments between d…
The impact of asteroid shapes and topographies on their reflectance spectroscopy
S. M. Potin, S. Douté, B. Kugler +1
We report the comparison between unresolved reflectance spectroscopy of Solar System small bodies and laboratory measurements on reference surfaces. We measure the bidirectional re…
An extended scattered light disk around AT Pyx -- Possible planet formation in a cometary globule
C. Ginski, R. Gratton, A. Bohn +35
To understand how the multitude of planetary systems that have been discovered come to be, we need to study systems at different evolutionary stages, with different central stars b…
Aqueous Alteration on Asteroids Simplifies Soluble Organic Matter Mixtures
Junko Isa, François-régis Orthous-Daunay, Pierre Beck +3
Biologically relevant abiotic extraterrestrial soluble organic matter (SOM) has been widely investigated to study the origin of life and the chemical evolution of protoplanetary di…
The HD 137496 system: A dense, hot super-Mercury and a cold Jupiter
T. Azevedo Silva, O. D. S. Demangeon, S. C. C. Barros +28
Most of the currently known planets are small worlds with radii between that of the Earth and that of Neptune. The characterization of planets in this regime shows a large diversit…
Neptune's ring arcs from VLT/SPHERE-IRDIS near-infrared observations
D. Souami, S. Renner, B. Sicardy +4
Neptune's incomplete ring arcs have been stable since their discovery in 1984 by stellar occultation. Although these structures should be destroyed within a few months through diff…
Narrow belt of debris around the Sco-Cen star HD 141011
M. Bonnefoy, J. Milli, F. Menard +22
We initiated a deep-imaging survey of Scorpius-Centaurus A-F stars with predicted warm inner and cold outer belts of debris reminiscent of the architecture of emblematic systems su…
Signs of late infall and possible planet formation around DR Tau using VLT/SPHERE and LBTI/LMIRCam
D. Mesa, C. Ginski, R. Gratton +31
Context. Protoplanetary disks around young stars often contain substructures like rings, gaps, and spirals that could be caused by interactions between the disk and forming planets…
Multiband imaging of the HD 36546 debris disk: a refined view from SCExAO/CHARIS
Kellen Lawson, Thayne Currie, John P. Wisniewski +21
We present the first multi-wavelength (near-infrared; ) imaging of HD 36546's debris disk, using the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system co…
Analysis of Early Science observations with the CHaracterising ExOPlanets Satellite (CHEOPS) using pycheops
P. F. L. Maxted, D. Ehrenreich, T. G. Wilson +77
CHEOPS(CHaracterising ExOPlanet Satellite) is an ESA S-class mission that observes bright stars at high cadence from low-Earth orbit. The main aim of the mission is to characterize…
The SuperCam Infrared Spectrometer for the Perseverance Rover of the Mars2020 mission
Thierry Fouchet, Jean-Michel Reess, Franck Montmessin +38
We present the Infrared spectrometer of SuperCam Instrument Suite that enables the Mars 2020 Perseverance Rover to study remotely the Martian mineralogy within the Jezero crater. T…
Volatile transport modeling on Triton with new observational constraints
T. Bertrand, E. Lellouch, B. J. Holler +18
Neptune's moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4 and CO, and represents a benchmark case for the study of surface-atmosphere interact…
EXPRES. III. Revealing the Stellar Activity Radial Velocity Signature of Eridani with Photometry and Interferometry
Rachael M. Roettenbacher, Samuel H. C. Cabot, Debra A. Fischer +20
The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) sh…
Mitigating stellar activity jitter with different line lists for least-squares deconvolution: analysis of a parametric and a randomised line selection
Stefano Bellotti, Pascal Petit, Julien Morin +5
Stellar activity limits the radial velocity search and characterisation of exoplanets, as it introduces spurious jitter in the data sets and prevents the correct retrieval of a pla…
