Multiplicity Boost of Transit Signal Classifiers: Validation of 69 New Exoplanets using the Multiplicity Boost of ExoMiner

The Astronomical Journal, 2023
Most existing exoplanets are discovered using validation techniques rather than being confirmed by complementary observations. These techniques generate a score that is typically the probability of the transit signal being an exoplanet ( y ( x ...

Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

The Astrophysical Journal Letters
Though missions such as Kepler, K2, and TESS have discovered >2000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in ( P ≲ 3 days) orbits. This feature, called the Neptune desert or the evaporation desert, is believed to be

The Impact of the Sulfur Allotropes and Sulfur Hydrides on the Venus Cloud Chemistry

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Venus is home to vivid sulfur chemistry, with SO2 ${\text{SO}}_{2}$ as the major sulfur gas species and a global cloud layer between 47 and 70 km composed of H2SO4 ${\mathrm{H}}_{2}{\text{SO}}_{4}$ and H2 ${\mathrm{H}}_{2}$O. The chemistry in the clouds has been extensively studied with 1D models, but none is able to reproduce the three orders

CoRoT pictures transiting exoplanets

, 2015
The detection and characterization of exoplanets have made huge progresses since the first discoveries in the late nineties. In particular, the independent measurement of the mass and radius of planets, by combining the transit and radial-velociy ...

Stellar activity as noise in exoplanet detection – I. Methods and application to solar-like stars and activity cycles [PDF]

, 2015
The detection of exoplanets using any method is prone to confusion due to the intrinsic variability of the host star. We investigate the effect of cool starspots on the detectability of the exoplanets around solar-like stars using the radial velocity ...
