cds-question@unistra.frinfrared-photometryvariable-starsRZ Piscium (RZ Psc) is well known in the variable star field because of its numerous irregular optical dips in the past 5 decades, but the nature of the system is heavily debated in the literature. We present multiyear infrared monitoring data from Spitzer and WISE to track the activities of the inner debris production, revealing stochastic infrared variability as short as weekly timescales that is consistent with destroying a 90km sized asteroid every year. ALMA 1.3mm data combined with spectral energy distribution modeling show that the disk is compact (~0.1-13au radially) and lacks cold gas. The disk is found to be highly inclined and has a significant vertical scale height. These observations confirm that RZ Psc hosts a close to edge-on, highly perturbed debris disk possibly due to migration of recently formed giant planets that might be triggered by the low-mass companion RZ Psc B if the planets formed well beyond the snowlines.2023ApJ...959...43Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/959/43CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/297 : AKARI/IRC mid-IR all-sky Survey (ISAS/JAXA, 2010)II/328 : AllWISE Data Release (Cutri+ 2013)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/350 : Gaia EDR3 (Gaia Collaboration, 2020)J/ApJ/688/1345 : Differential phot. of the SB* BD+20 307 (Zuckerman+, 2008)J/ApJ/792/30 : NEOWISE magnitudes for near-Earth objects (Mainzer+, 2014)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/ApJ/805/77 : Spitzer 3.6 and 4.5um monitoring of 5 stars (Meng+, 2015)J/AJ/157/202 : IRAC fluxes of the ID8 and P1121 systems (Su+, 2019)J/MNRAS/488/3588 : Debris discs in medium separation bin.
