GP model fit to the RV data. Left panel shows the entire RV time series in black and the GP model in blue, with residuals plotted in the lower panel, to demonstrate that a quasiperiodic GP model was able to capture the long-period variation caused by the stellar magnetic cycle. The gray shaded region is shown in the right panel. The right panel shows the same model and data over a centrally located 60 day baseline, to highlight the effects of the 9.42 day stellar rotation period. -- astro-ph.EP

The Magnetically Induced Radial Velocity Variation of Gliese 341 and an Upper Limit to the Mass of Its Transiting Earth-sized Planet

by Keith CowingFebruary 13, 2025February 13, 2025

The Transiting Exoplanet Survey Satellite (TESS) mission identified a potential 0.88 REarth planet with a period of 7.577 days, orbiting the nearby M1V star GJ 341 (TOI 741.01).

The light curves and best fit models resulting from the Eureka! pipeline. The columns show, from left to right: transit 1, transit 2, transit 3. The rows show, from top to bottom: 1) the white light curve and residuals, 2) the spectroscopic light curves, 3) the best-fit models to the spectroscopic light curves, 4) the residuals from the spectroscopic light curve fitting. -- astro-ph.EP

JWST/NIRCam Transmission Spectroscopy Of The Nearby Sub-Earth GJ 341b

by Keith CowingJanuary 12, 2024January 12, 2024

We present a JWST/NIRCam transmission spectrum from 3.9−5.0 μm of the recently-validated sub-Earth GJ 341b (RP=0.92 R⊕, Teq=540 K) orbiting a nearby bright M1 star (d=10.4 pc, Kmag=5.6).
