A time-aware convolutional attention network trained on StarSim synthetic spectra reduces stellar activity radial velocity jitter to 52.5% and 62.4% of original levels in HARPS and CARMENES data for epsilon Eridani and TZ Arietis.
TOI-4311 hosts a 0.99-day super-Earth (1.38 R_earth, 4.5 M_earth) and 15-day sub-Neptune (2.47 R_earth), plus a candidate 38-day planet, with the dense inner planet potentially challenging formation theories given the host's galactic population.
Interpolation algorithm choice in template-based RV extraction from high-resolution spectra introduces systematic biases reaching 20-25 m/s in low-SNR cases and under 0.2 m/s when BERV variation is large, demonstrated via Gaussian synthetic spectra and ESPRESSO observations.
Three massive planets detected around HD125136 (2.26 MJup, 850 d) and HD127195 (0.66 and 0.78 MJup, 535 d and 834 d) via Bayesian Keplerian modeling of CORALIE RV series; one additional signal attributed to activity.
