Uncovering temperate worlds: an updated look at the K2-3 system with ESPRESSO
Avidaan Srivastava, Emma Pimentel, Amélie Gressier +24
The K2-3 system is one of the most unique planetary systems as it features three transiting sub-Neptunes in decreasing order of radii, spanning the radius valley. In addition to th…
Effect of stellar spot-only spectral lines in high-resolution transit spectroscopy
W. Dethier, E. Cristo, O. D. S. Demangeon +3
We investigate how a representative single spectral line present only in a stellar spot can introduce distortions in high-resolution planetary absorption spectra. Specifically, we…
Predicting Radial Velocities from Rossiter-McLaughlin Time Series Observations
Vardan Adibekyan, Olivier Demangeon, Diogo Teixeira +7
The Rossiter-McLaughlin (RM) effect produces apparent radial velocity (RV) shifts through line-profile distortions caused by a transiting planet blocking different regions of the r…
Reinforcing Prestige: Journal Citation Biases in Astronomy
Vardan Adibekyan, Olivier Demangeon, Tiago Campante +3
Citations are essential for recognizing scientific contributions, yet citation behavior is shaped by more than just relevance or quality. We analyzed approximately 255,000 refereed…
PoET: the Paranal solar ESPRESSO Telescope
Nuno C. Santos, Alexandre Cabral, Inês Leite +42
The detection and characterisation of other "Earths", orbiting other suns, is a bold objective of present-day astrophysics. However, this quest is severely challenged by astrophysi…
Exploring the Neptunian Desert: Insights from a Homogeneous Planetary Sample
Lauren Doyle, David J. Armstrong, Lorena Acuña +26
In this paper, we present a homogeneous analysis of close-in Neptune planets. To do this, we compile a sample of TESS-observed planets using a ranking criterion which takes into ac…
TOI-1408: Discovery and Photodynamical Modeling of a Small Inner Companion to a Hot Jupiter Revealed by TTVs
Judith Korth, Priyanka Chaturvedi, Hannu Parviainen +60
We report the discovery and characterization of a small planet, TOI-1408 c, on a 2.2-day orbit located interior to a previously known hot Jupiter, TOI-1408 b ( d, $M=1.86\p…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Giant Outer Transiting Exoplanet Mass (GOT 'EM) Survey: III. Recovery and Confirmation of a Temperate, Mildly Eccentric, Single-Transit Jupiter Orbiting TOI-2010
Christopher R. Mann, Paul A. Dalba, David Lafrenière +48
Large-scale exoplanet surveys like the TESS mission are powerful tools for discovering large numbers of exoplanet candidates. Single-transit events are commonplace within the resul…
A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS
Thomas G. Wilson, Elisa Goffo, Yann Alibert +132
We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise…
TOI-1431b/MASCARA-5b: A Highly Irradiated Ultra-Hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars
Brett Christopher Addison, Emil Knudstrup, Ian Wong +70
We present the discovery of a highly irradiated and moderately inflated ultra-hot Jupiter, TOI-1431b/MASCARA-5b (HD 201033b), first detected by NASA's Transiting Exoplanet Survey S…
ARCHI: pipeline for light curve extraction of CHEOPS background star
André M. Silva, Sérgio G. Sousa, Nuno Santos +6
High precision time series photometry from space is being used for a number of scientific cases. In this context, the recently launched CHEOPS (ESA) mission promises to bring 20 pp…
Improving transit characterisation with Gaussian process modelling of stellar variability
S. C. C. Barros, O. Demangeon, R. F. Díaz +4
New photometric space missions to detect and characterise transiting exoplanets are focusing on bright stars to obtain high cadence, high signal-to-noise light curves. Since these…
Gaussian Process modelling of granulation and oscillations in red-giant stars
Filipe Pereira, Tiago L. Campante, Margarida S. Cunha +6
The analysis of photometric time series in the context of transiting planet surveys suffers from the presence of stellar signals, often dubbed "stellar noise". These signals, cause…
Synergy between asteroseismology and exoplanet science: an outlook
Tiago L. Campante, Susana C. C. Barros, Olivier Demangeon +5
Space-based asteroseismology has been playing an important role in the characterization of exoplanet-host stars and their planetary systems. The future looks even brighter, with sp…
K2 Targets Observed with SPHERE/VLT: An M4-7 Dwarf Companion Resolved around EPIC 206011496
Roxanne Ligi, Olivier Demangeon, Susana Barros +6
The quest to discover exoplanets is one of the most important missions in astrophysics, and is widely performed using the transit method, which allows for the detection of exoplane…
KPS-1b: the first transiting exoplanet discovered using an amateur astronomer's wide-field CCD data
Artem Burdanov, Paul Benni, Eugene Sokov +19
We report the discovery of the transiting hot Jupiter KPS-1b. This exoplanet orbits a V=13.0 K1-type main-sequence star every 1.7 days, has a mass of $M_{…
Distinguishing the albedo of exoplanets from stellar activity
L. M. Serrano, S. C. C. Barros, M. Oshagh +5
Light curves show the flux variation from the target star and its orbiting planets as a function of time. In addition to the transit features created by the planets, the flux also…
