The large sieve inequality and additive decompositions of sums of squares

Christian Elsholtz, Julia Stadlmann

Building on the large sieve, we prove a new sieve estimate for sets which are missing various residue classes modulo prime squares. For certain interesting residue class configurat…

A temperate sub-Neptune transiting the M4 Dwarf TOI-210 identified by NIRPS and TESS -- Uncovering hidden M-dwarf planetary systems in the near-infrared

C. Cadieux, B. N. Skinner, F. Bouchy +63

Super-Earths and sub-Neptunes dominate the exoplanet population, yet their compositions, formation mechanisms, and capability of retaining atmospheres remain poorly understood. M-t…

Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS

Y. Carteret, V. Bourrier, L. Parc +57

The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…

Uncovering temperate worlds: an updated look at the K2-3 system with ESPRESSO

Avidaan Srivastava, Emma Pimentel, Amélie Gressier +24

The K2-3 system is one of the most unique planetary systems as it features three transiting sub-Neptunes in decreasing order of radii, spanning the radius valley. In addition to th…

A Candidate Innermost Fifth Planet In the HR 8799 System Revealed By JWST NIRISS Aperture Masking Interferometry

Jayke S. Nguyen, Louis Desdoigts, Alexandra Z. Greenbaum +20

We detect a candidate fifth planet in the HR 8799 system, directly imaged with the JWST/NIRISS Aperture Masking Interferometer (AMI). The detected source lies just above a con…

Night-sky emission correction techniques for high-resolution spectroscopy: Demonstration with NIRPS

Avidaan Srivastava, François Bouchy, Xavier Dumusque +54

Ground-based spectrographs operating in the near-infrared (NIR) regime are hampered by various absorption and emission features of Earth's atmosphere. While considerable attention…
