Kilometre-scale Jovian moon characterized for a potential JUICE flyby
Juan Luis Rizos, Jose Maria Gomez-Limon, Yucel Kilic +51
Jupiter's irregular satellites are thought to be relics of early Solar System planetesimals. However, their small sizes, large distances from Earth and close angular proximity to J…
Constraining the size, shape, and albedo of the large Trans-Neptunian Object (28978) Ixion with multi-chord stellar occultations
Y. Kilic, F. Braga-Ribas, C. L. Pereira +81
Trans-Neptunian objects (TNOs) are among the most primitive remnants of the early Solar System, and constraining their sizes, shapes, albedos, and surface properties is essential f…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
Confirmation of four hot Jupiters detected by TESS using follow-up spectroscopy from MaHPS at Wendelstein together with NEID and TRES
Juliana Ehrhardt, Luis Thomas, Hanna Kellermann +57
We report the confirmation and characterization of four hot Jupiter-type exoplanets initially detected by TESS: TOI-1295 b, TOI-2580 b, TOI-6016 b, and TOI-6130 b. Using observatio…
ExoClock Project III: 450 new exoplanet ephemerides from ground and space observations
A. Kokori, A. Tsiaras, B. Edwards +214
The ExoClock project has been created with the aim of increasing the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides o…
GRANDMA Observations of ZTF/Fink Transients during Summer 2021
V. Aivazyan, M. Almualla, S. Antier +80
We present our follow-up observations with GRANDMA of transient sources revealed by the Zwicky Transient Facility (ZTF). Over a period of six months, all ZTF triggers were examined…
A Possible Alignment Between the Orbits of Planetary Systems and their Visual Binary Companions
Sam Christian, Andrew Vanderburg, Juliette Becker +111
Astronomers do not have a complete picture of the effects of wide-binary companions (semimajor axes greater than 100 AU) on the formation and evolution of exoplanets. We investigat…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
ExoClock project II: A large-scale integrated study with 180 updated exoplanet ephemerides
A. Kokori, A. Tsiaras, B. Edwards +102
The ExoClock project is an inclusive, integrated, and interactive platform that was developed to monitor the ephemerides of the Ariel targets to increase the mission efficiency. Th…
TOI-1518b: A Misaligned Ultra-hot Jupiter with Iron in its Atmosphere
Samuel H. C. Cabot, Aaron Bello-Arufe, João M. Mendonça +36
We present the discovery of TOI-1518b -- an ultra-hot Jupiter orbiting a bright star . The transiting planet is confirmed using high-resolution optical transmission spect…
Fragmentation modelling of the August 2019 impact on Jupiter
Ramanakumar Sankar, Csaba Palotai, Ricardo Hueso +3
On 7th August 2019, an impact flash lasting s was observed on Jupiter. The video of this event was analysed to obtain the lightcurve and determine the energy release and ini…
Saturn atmospheric dynamics one year after Cassini: Long-lived features and time variations in the drift of the Hexagon
R. Hueso, A. Sánchez-Lavega, J. F. Rojas +15
We examine Saturn's atmosphere with observations from ground-based telescopes and Hubble Space Telescope (HST). We present a detailed analysis of observations acquired during 2018.…
The onset and growth of the 2018 Martian Global Dust Storm
Agustín Sánchez-Lavega, Teresa del Río-Gaztelurrutia, Jorge Hernández-Bernal +1
We analyze the onset and initial expansion of the 2018 Martian Global Dust Storm (GDS 2018) using ground-based images in the visual range. This is the first case of a confirmed GDS…
Small impacts on the giant planet Jupiter
R. Hueso, M. Delcroix, A. Sánchez-Lavega +8
Video observations of Jupiter obtained by amateur astronomers over the past eight years have shown five flashes of light of 1-2 s. The first three of these events occurred on 3 Jun…
Neptune long-lived atmospheric features in 2013-2015 from small (28-cm) to large (10-m) telescopes
R. Hueso, I. de Pater, A. Simon +32
Since 2013, observations of Neptune with small telescopes have resulted in several detections of long-lived bright atmospheric features that have also been observed by large telesc…
Early evolution of the extraordinary Nova Del 2013 (V339 Del)
A. Skopal, H. Drechsel, T. N. Tarasova +14
We determine the temporal evolution of the luminosity L(WD), radius R(WD) and effective temperature Teff of the white dwarf (WD) pseudophotosphere of V339 Del from its discovery to…
Groupes Classiques
Baptiste Calmès, Jean Fasel
We introduce so-called "classical" algebraic group over a general base scheme, and then place them where they belong in the classification of reductive groups established in SGA3.…
Contribution of amateur observations to Saturn storm studies
Marc Delcroix, Georg Fischer
Since 2004, Saturn Electrostatic Discharges (SEDs), which are the radio signatures of lightning in Saturn's atmosphere, have been observed by the Cassini Radio and Plasma Wave Scie…
