Impact of embedded circumplanetary winds on the circumstellar disk: I. Reshaping the local accretion environment
Danilo Sepúlveda-Rojas, Pablo Benítez-Llambay, Simon Casassus
The existence of winds is among the uncertainties related to the growth of giant planets. Such circumplanetary outflows have been proposed to explain kinematic and chemical structu…
Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b
S. Ulmer-Moll, S. Gill, R. Brahm +64
Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…
Polycyclic aromatic hydrocarbon (PAH) abundances in the disk around T Chamaeleontis (T Cha): PAH sizes, ionization fraction, and mass during JWST observations
Rahul Bandyopadhyay, Simon Casassus
The T Tauri star T Cha is known to have a protoplanetary disk with a dust gap separating the inner and outer disk regions. The mid-infrared JWST spectrum of T Cha shows multiple pr…
TOI-2005b: An Eccentric Warm Jupiter in Spin-Orbit Alignment
Allyson Bieryla, Jiayin Dong, George Zhou +36
We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was de…
Exoplanet Transit Candidate Identification in TESS Full-Frame Images via a Transformer-Based Algorithm
Helem Salinas, Rafael Brahm, Greg Olmschenk +4
The Transiting Exoplanet Survey Satellite (TESS) is surveying a large fraction of the sky, generating a vast database of photometric time series data that requires thorough analysi…
NGTS-EB-7, an eccentric, long-period, low-mass eclipsing binary
Toby Rodel, Christopher. A. Watson, Solène Ulmer-Moll +35
Despite being the most common types of stars in the Galaxy, the physical properties of late M dwarfs are often poorly constrained. A trend of radius inflation compared to evolution…
Spectroscopic observations of flares and superflares on AU Mic
P. Odert, M. Leitzinger, R. Greimel +13
The young active flare star AU~Mic is the planet host star with the highest flare rate from TESS data. Therefore, it represents an ideal target for dedicated ground-based monitorin…
TOI-4504: Exceptionally large Transit Timing Variations induced by two resonant warm gas giants in a three planet system
Michaela Vítková, Rafael Brahm, Trifon Trifonov +24
We present a joint analysis of TTVs and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known transit…
A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b
A. L. Carter, E. M. May, N. Espinoza +77
Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…
ATAT: Astronomical Transformer for time series And Tabular data
G. Cabrera-Vives, D. Moreno-Cartagena, N. Astorga +14
The advent of next-generation survey instruments, such as the Vera C. Rubin Observatory and its Legacy Survey of Space and Time (LSST), is opening a window for new research in time…
The EBLM Project XII. An eccentric, long-period eclipsing binary with a companion near the hydrogen-burning limit
Yasmin T. Davis, Amaury H. M. J. Triaud, Alix V. Freckelton +17
In the hunt for Earth-like exoplanets it is crucial to have reliable host star parameters, as they have a direct impact on the accuracy and precision of the inferred parameters for…
The Aligned Orbit of the Eccentric Proto Hot Jupiter TOI-3362b
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +8
High-eccentricity tidal migration predicts the existence of highly eccentric proto-hot Jupiters on the "tidal circularization track," meaning that they might eventually become hot…
Orbital alignment of the eccentric warm Jupiter TOI-677 b
Elyar Sedaghati, Andrés Jordán, Rafael Brahm +3
Warm Jupiters lay out an excellent laboratory for testing models of planet formation and migration. Their separation from the host star makes tidal reprocessing of their orbits ine…
Resolving the Binary Components of the Outbursting Protostar HBC 494 with ALMA
Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez +15
Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevat…
RAM: Rapid Advection Algorithm on Arbitrary Meshes
Pablo Benítez-Llambay, Leonardo Krapp, Ximena S. Ramos +1
The study of many astrophysical flows requires computational algorithms that can capture high Mach number flows, while resolving a large dynamic range in spatial and density scales…
Gas distribution in ODISEA sources from ALMA long-baseline observations in CO(2-1)
Juanita Antilen, Simon Casassus, Lucas A. Cieza +1
The CO rotational lines in protoplanetary discs are good tracers of the total spatial extension of the gas component, and potentially planet-disc interactions. We present AL…
Distinguishing a planetary transit from false positives: a Transformer-based classification for planetary transit signals
Helem Salinas, Karim Pichara, Rafael Brahm +2
Current space-based missions, such as the Transiting Exoplanet Survey Satellite (TESS), provide a large database of light curves that must be analysed efficiently and systematicall…
