Predictions of Transiting Exoplanet Confirmations from Rubin LSST Surveys

Suber Corley, Eric D. Feigelson, C. Cáceres, Bolivia Cuevas-Otahola et autres

Abstract We assess the prospects for exoplanet transit observations in the 10 yr Wide Fast Deep (WFD) and Deep Drilling Field (DDF) surveys within the Legacy Survey of Space and Time mission of the Vera C. Rubin Observatory. We construct a framework …

Discovery of planetary-mass binaries in the Lower Centaurus-Crux association

C. Cáceres, D. Minniti, Andrea Mejías, M. Gómez et autres

Context . The recent discovery of free-floating planets (FFPs) in nearby young stellar associations suggests that these objects might be common in the Galaxy. Our search for FFPs in the young Lower Centaurus-Crux (LCC) association using the VISTA Variables in the Vía …

Gaia-VVVX search for M-type variable stars in young nearby open clusters

Dante Minniti, M. López, J. Alonso-García, M. Cortés-Contreras et autres

Context . While large samples of nearby M dwarfs are becoming available, it is usually difficult to estimate some intrinsic physical parameters for isolated field M dwarfs, especially their ages, radii, and masses. These parameters can be estimated through a comparison with …

Horizontal and vertical exoplanet thermal structure from a JWST spectroscopic eclipse map

Ryan C. Challener, Megan Mansfield, Patricio E. Cubillos, Anjali A. A. Piette et autres

Highly irradiated giant exoplanets known 'ultrahot Jupiters' are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, latitude and altitude. Previous observations have hinted at these variations, but the existing data have been fundamentally restricted to …

Testing the performance of cross-correlation techniques to search for molecular features in JWST NIRSpec G395H observations of transiting exoplanets

E. Esparza-Borges, Mercedes López‐Morales, Ε. Πάλλη, Vladimir Yu. Makhnev et autres

ABSTRACT Cross-correlations techniques offer an alternative method to search for molecular species in James Webb Space Telescope (JWST) observations of exoplanet atmospheres. In a previous article, we applied cross-correlation functions for the first time to JWST NIRSpec/G395H observations of exoplanet atmospheres, resulting …

Confirmation of a ring structure in the disk around MP Mus (PDS 66) with ALMA Band 7 observations

A. Aguayo, C. Cáceres, Zhen Guo, M. R. Schreiber et autres

Context. Young stellar objects (YSOs) are surrounded by protoplanetary disks, which are the birthplace of young planets. Ring and gap structures are observed among evolved protoplanetary disks, often interpreted as a consequence of planet formation. Aims. The pre-Main Sequence (pre-MS) star MP …

The young exoplanetary system TOI-4562: Confirming the presence of a third body in the system

V. Fermiano, R. K. Saito, V. D. Ivanov, C. Cáceres et autres

Context. Young planetary systems represent an opportunity to investigate the early stages of (exo)planetary formation because the gravitational interactions have not yet significantly changed the initial configuration of the system. Aims. TOI-4562 b is a highly eccentric temperate Jupiter analogue orbiting a …

The Empirical and Radiative Transfer Hybrid (EaRTH) Disk Model: Merging Analyses of Protoplanetary Dust Disk Mineralogy and Structure

W. Grimble, Joel H. Kastner, C. Pinte, Beth A. Sargent et autres

Abstract Our understanding of how exoplanets form and evolve relies on analyses of both the mineralogy of protoplanetary disks and their detailed structures; however, these key complementary aspects of disks are usually studied separately. We present initial results from a hybrid model …

A benchmark JWST near-infrared spectrum for the exoplanet WASP-39 b

Aarynn L. Carter, Erin May, Néstor Espinoza, Luis Welbanks et autres

Abstract Observing exoplanets through transmission spectroscopy supplies detailed information about their atmospheric composition, physics and chemistry. Before the James Webb Space Telescope (JWST), these observations were limited to a narrow wavelength range across the near-ultraviolet to near-infrared, alongside broadband photometry at longer …

The VISTA Variables in the Vía Láctea extended (VVVX) ESO public survey: Completion of the observations and legacy

R. K. Saito, M. Hempel, J. Alonso-García, P. W. Lucas et autres

Context. The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from 2009–2015. Upon its conclusion, the complementary VVV extended (VVVX) survey has expanded both the temporal as well as …

R. K. Saito, M. Hempel, J. Alonso-García, P. W. Lucas et autres

The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from $2009-2015$. Upon its conclusion, the complementary VVV eXtended (VVVX) survey has expanded both the temporal as well as spatial …
