RZ Psc Archives

Top: Simulated EVE observation of an exocomet transit of a K7V at 100 pc expected during a 20 d stare at ∼20 Myr Theia 43 or 45 associations. We scale the optical light curve template used for the RZ Psc events into the NUV and NIR bands using a 50-50% weighted average of empirical extinction curves of ∼200 nm water ice (Kratschmer & Sorg 1985) and olivine dust (Huffman 1975). Bottom: Distribution of optical ADs versus SpT for 590 simulated detections. The SNR of the NUV detections (left) enable color differences due to composition (middle) and grain size (right) to be distinguished given the color predictions for the narrow-tail multiband comet models of K´alm´an et al. (2024). Each panel highlights the region in which EVE should detect exocomets given a 20% M-star disk fraction, but not for a 2.1% fraction. -- astro-ph.EP

TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc

by Keith CowingOctober 22, 2025October 22, 2025

We present the TESS discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling […]
