Exoplanet detection in angular differential imaging: combining a statistics-based learning with a deep-based learning for improved detections

Astronomical Telescopes + Instrumentation, 2022
Direct imaging is an active research topic in astronomy for the detection and the characterization of young substellar objects. The very high contrast between the host star and its companions makes detection particularly challenging.

The Comparison of Five Methods of Detecting Exoplanets

Highlights in Science, Engineering and Technology, 2023
Detecting exoplanets has become a hot topic, where various detection scenarios have been proposed. Five of these methods have all found more than 50 exoplanets, which are the transit method, the radial velocity method, the microlensing method, the imaging method, and the timing method.

3D magneto-hydrodynamical simulations of stellar convective noise for improved exoplanet detection [PDF]

Astronomy & Astrophysics, 2020
Context. Convective motions at the stellar surface generate a stochastic colored noise source in the radial velocity (RV) data. This noise impedes the detection of small exoplanets.

Hyades Member K2-136c: The Smallest Planet in an Open Cluster with a Precisely Measured Mass

The Astronomical Journal, 2023
K2-136 is a late-K dwarf (0.742 ± 0.039 M _⊙ ) in the Hyades open cluster with three known, transiting planets and an age of 650 ± 70 Myr. Analyzing K2 photometry, we found that planets K2-136b, c, and d have periods of 8.0, 17.3, and 25.6 days and radii

Asteroseismology of Exoplanet Host Stars

, 2015
Asteroseismology is among the most powerful observational tools to determine fundamental properties of stars. Space-based photometry has recently enabled the systematic detection of oscillations in exoplanet host stars, allowing a combination of ...

The Rossiter-McLaughlin effect in Exoplanet Research

, 2017
The Rossiter-McLaughlin effect occurs during a planet's transit. It provides the main means of measuring the sky-projected spin-orbit angle between a planet's orbital plane, and its host star's equatorial plane.
