A SPHEREx Pipeline and Spectral Library for Ultracool Dwarfs

Jonathan Gagné, Jacqueline K. Faherty, Azul Ruiz Diaz +72

We present a Python spectrophotometry extraction tool tailored for fast-moving point sources detected in the SPHEREx mission, and use it to construct a set of 0.75-5.0 m low-res…

NGTS-EB-8: A double-lined eclipsing M+M binary discovered by citizen scientists

Sean M. O'Brien, Megan E. Schwamb, Christopher A. Watson +54

We report the identification and characterization of a new binary system composed of two near-equal mass M-dwarfs. The binary NGTS-EB-8 was identified as a planet candidate in data…

Planet Hunters TESS V: a planetary system around a binary star, including a mini-Neptune in the habitable zone

Nora L. Eisner, Samuel K. Grunblatt, Oscar Barragán +61

We report on the discovery and validation of a transiting long-period mini-Neptune orbiting a bright (V = 9.0 mag) G dwarf (TOI 4633; R = 1.05 RSun, M = 1.10 MSun). The planet was…
