Evolution of the Exoplanet Size Distribution: Forming Large Super-Earths Over Billions of Years
Trevor J. David, Gabriella Contardo, Angeli Sandoval +9
The radius valley, a bifurcation in the size distribution of small, close-in exoplanets, is hypothesized to be a signature of planetary atmospheric loss. Such an evolutionary pheno…
Excalibur: A Non-Parametric, Hierarchical Wavelength-Calibration Method for a Precision Spectrograph
L. L. Zhao, D. W. Hogg, M. Bedell +1
Excalibur is a non-parametric, hierarchical framework for precision wavelength-calibration of spectrographs. It is designed with the needs of extreme-precision radial velocity (EPR…
How magnetic activity alters what we learn from stellar spectra
Lorenzo Spina, Thomas Nordlander, Andrew R. Casey +8
Magnetic fields and stellar spots can alter the equivalent widths of absorption lines in stellar spectra, varying during the activity cycle. This also influences the information th…
Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +11
Low frequency (MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission…
No Massive Companion to the Coherent Radio-Emitting M Dwarf GJ 1151
Benjamin J. S. Pope, Megan Bedell, Joseph R. Callingham +4
The recent detection of circularly polarized, long-duration (>8 hr) low-frequency (~150 MHz) radio emission from the M4.5 dwarf GJ 1151 has been interpreted as arising from a star-…
The Young Planet DS Tuc Ab has a Low Obliquity
Benjamin T. Montet, Adina D. Feinstein, Rodrigo Luger +9
The abundance of short-period planetary systems with high orbital obliquities relative to the spin of their host stars is often taken as evidence that scattering processes play imp…
