Revised Masses for Low-density Planets Orbiting the Disordered M-dwarf System TOI-1266

The Astronomical Journal
We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two known transiting sub-Neptunes at 10.8 and 18.8 days.

Migration and Evolution of giant ExoPlanets (MEEP). I. Nine Newly Confirmed Hot Jupiters from the TESS Mission

The Astronomical Journal
Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery the mysteries surrounding their origins have remained. Here we present nine new hot Jupiters (TOI-1855 b, TOI-2107 b, TOI-2368 b, TOI-3321 b,

Deep Space Insights: Machine Learning Revolutionizing Astrophysical Discoveries [PDF]

EPJ Web of Conferences
This paper examines the transformative role of machine learning (ML) in astrophysics. With the exponential growth of astronomical data, traditional methods are often insufficient for effective data management and analysis.

Searching for Giant Exoplanets around M-dwarf Stars (GEMS) I: Survey Motivation

The Astronomical Journal
Recent discoveries of transiting giant exoplanets around M-dwarf stars (GEMS), aided by the all-sky coverage of TESS, are starting to stretch theories of planet formation through the core-accretion scenario.

Revised Architecture and Two New Super-Earths in the HD 134606 Planetary System

The Astronomical Journal
Multiplanet systems exhibit a diversity of architectures that diverge from the solar system and contribute to the topic of exoplanet demographics. Radial velocity (RV) surveys form a crucial component of exoplanet surveys, as their long observational ...

Single Transit Detection in Kepler with Machine Learning and Onboard Spacecraft Diagnostics

The Astronomical Journal
Exoplanet discovery at long orbital periods requires reliably detecting individual transits without additional information about the system. Common techniques, like phase folding of light curves and periodogram analysis of radial velocity data, are more ...

TESS Hunt for Young and Maturing Exoplanets (THYME). XII. A Young Mini-Neptune on the Upper Edge of the Radius Valley in the Hyades Cluster

The Astronomical Journal
We present the discovery and characterization of TOI-4364b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit observations and ground-based follow-up photometry.
