A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f
Juliana GarcÃa-MejÃa, Zoë L. de Beurs, Patrick Tamburo +25
We present a ground-based transit detection of HIP 41378 f, a long-period ( days), extremely low-density ( g cm) giant exoplanet in a dynamically com…
Identifying Exoplanets with Deep Learning VI. Enhancing neural network mitigation of stellar activity RV signals with additional metrics
Naomi McWilliam, Zoë L. de Beurs, Andrew Vanderburg +12
The measurement of exoplanet masses using the radial velocity (RV) technique is currently limited by stellar activity, which introduces quasiperiodic variability signals that must…
MANGOS II: Five new giant planets orbiting low-mass stars
G. Dransfield, M. Timmermans, D. Sebastian +47
Giant planets orbiting low-mass stars on short orbits present a conundrum, as in the most extreme cases their existence cannot be reconciled with current models of core accretion.…
A New Brown Dwarf Orbiting an M star and An Investigation on the Eccentricity Distribution of Transiting Long-Period Brown Dwarfs
Tianjun Gan, Charles Cadieux, Shigeru Ida +32
The orbital eccentricities of brown dwarfs encode valuable information of their formation and evolution history, providing insights into whether they resemble giant planets or stel…
A long spin period for a sub-Neptune-mass exoplanet
Ellen M. Price, Juliette Becker, Zoë L. de Beurs +2
HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically…
LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network
Javier Viaña, Kyu-Ha Hwang, Zoë de Beurs +20
Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time-consuming. This reliance on manual inspection often le…
