Semianalytical Accretion-tracer Emission: Forming Planets Are Intrinsically Faint

open access: yesThe Astrophysical Journal
Direct-imaging surveys have looked for accreting planets through their accretion tracers such as H α but have been less fruitful than expected.

The Roman Microlensing Survey: Confirmation or Refutation of Gas Giant Exoplanet Formation Theories

open access: yesThe Astrophysical Journal
Exoplanet research has moved from the discovery of new classes of planets toward creating a census of exoplanet population demographics across the spectrum of exoplanet and host star masses.

Exoplanetary systems

open access: yes, 2021
Beyond the Solar System there are more than 3000 stellar systems composed of since dwarfs to supergiant stars, orbited by more than 4000 exoplanets divided in several types, small and rocky, giant and gaseous, some of which are not seen in the Solar ...

The Heating Efficiency of Hot Jupiters from a Data-driven Perspective

open access: yesThe Astronomical Journal
The inflated radii of hot Jupiters have been explored by various theoretical mechanisms. By connecting planetary thermal evolution models with the observed properties of hot Jupiters using hierarchical Bayesian models, a theoretical parameter called the ...

Restricciones bayesianas sobre las propiedades observables de los sistemas exoplanetarios utilizando simulaciones de síntesis de población planetaria

open access: yes, 2021
Ilustraciones y tablasRecent advances in exoplanet observations have led to the discovery of nearly 4400 planets in more than 3000 planetary systems. However, many physical properties of these systems remain largely unknown due to observational biases ...

Relative Occurrence Rate between Hot and Cold Jupiters as an Indicator to Probe Planet Migration

open access: yesThe Astrophysical Journal
We propose a second-order statistic parameter ε , the relative occurrence rate between hot Jupiters (HJs) and cold Jupiters (CJs) ( ε = η _HJ / η _CJ ), to probe the migration of gas giants. Since the planet occurrence rate is the combined outcome of the
