Deep-learning based measurement of planetary radial velocities in the presence of stellar variability
Ian Colwell, Virisha Timmaraju, Alexander Wise
We present a deep-learning based approach for measuring small planetary radial velocities in the presence of stellar variability. We use neural networks to reduce stellar RV jitter…
Spectral Line Depth Variability in Radial Velocity Spectra
Alexander Wise, Peter Plavchan, Xavier Dumusque +2
Stellar active regions, including spots and faculae, can create radial velocity (RV) signals that interfere with the detection and mass measurements of low mass exoplanets. In doin…
New Methods for Finding Activity-Sensitive Spectral Lines: Combined Visual Identification and an Automated Pipeline Find a Set of 40 Activity Indicators
A. W. Wise, S. E. Dodson-Robinson, K. Bevenour +1
Starspots, plages, and activity cycles cause radial velocity variations that can either mimic planets or hide their existence. To verify the authenticity of newly discovered planet…
No Giant Planet Pileup Near 1 AU
Alexander W. Wise, Sarah E. Dodson-Robinson
A pileup near 1~AU in the semimajor axis distribution of giant exoplanets has been visually identified using log-spaced distribution plots. Here we propose that looking for feature…
Photoevaporation Does Not Create a Pileup of Giant Planets at 1 AU
Alexander W. Wise, Sarah E. Dodson-Robinson
The semimajor axis distribution of giant exoplanets appears to have a pileup near 1 AU. Photoevaporation opens a gap in the inner few AU of gaseous disks before dissipating them. H…
