Trade-offs in high-contrast integral field spectroscopy for exoplanet detection and characterisation. Young gas giants in emission [PDF]
Astronomy & Astrophysics, 2023 Context: Combining high-contrast imaging with medium- or high-resolution integral field spectroscopy has the potential to boost the detection rate of exoplanets, especially at small angular separations.

OGLE-2019-BLG-1180Lb: Discovery of a Wide-orbit Jupiter-mass Planet around a Late-type Star
The Astronomical Journal, 2023 We report on the discovery and analysis of the planetary microlensing event OGLE-2019-BLG-1180 with a planet-to-star mass ratio q ∼ 0.003. The event OGLE-2019-BLG-1180 has unambiguous cusp-passing and caustic-crossing anomalies, which were caused by a ...

A new estimation of astrometric exoplanet detection limits in the habitable zone around nearby stars [PDF]
Astronomy & Astrophysics, 2022 Context. Astrometry is less sensitive to stellar activity than the radial velocity technique when attempting to detect Earth mass planets in the habitable zone of solar-type stars.

A continuous multiple hypothesis testing framework for optimal exoplanet detection [PDF]
Annals of Applied Statistics, 2022 When searching for exoplanets, one wants to count how many planets orbit a given star, and to determine what their characteristics are. If the estimated planet characteristics are too far from those of a planet truly present, this should be considered as

Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets
The Astronomical Journal, 2023 We complete the publication of all microlensing planets (and “possible planets”) identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields during the 2019 observing season, namely, KMT-2019-BLG-0298, KMT-2019-BLG ...

Improving exoplanet detection capabilities with the false inclusion probability. Comparison with other detection criteria in the context of radial velocities [PDF]
Astronomy & Astrophysics, 2021 Context. It is common practice to claim the detection of a signal if, for a certain statistical significance metric, the signal significance exceeds a certain threshold fixed in advance.
