Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy
K. Fukushima, L. Hirata, N. Y. Yamasaki +17
We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…
Constraints on the Crystallinity of Water Ice in Planet-forming Disks from Infrared Scattered-Light Spectra
Kanon Nakazawa, Ryo Tazaki
The crystallinity of water ice not only records the thermal history experienced by an astronomical body, but also affects the composition of forming planets by controlling the trap…
High-resolution X-ray spectroscopy with XRISM/Resolve reveals super-Solar abundance ratios in Virgo/M87
J. Martin, A. Simionescu, F. Mernier +26
The chemical composition of the intracluster medium (ICM) provides key insights into the enrichment history of galaxy clusters. However, high-resolution abundance measurements with…
Sulfur Enrichment in Close-in Exoplanet Atmospheres Induced by Pebble Drift across the Salt Line
Kanon Nakazawa, Kazumasa Ohno
Observations of JWST have revealed that several close-in exoplanets have sulfur-rich atmospheres through SO detections. Atmospheric sulfur is often thought to originate from so…
Nitrogen transport in protoplanetary disks by ammonium salts: a possible origin of Jupiter's nitrogen enrichment
Kanon Nakazawa, Satoshi Okuzumi
Atmospheric compositions preserve the history of planet formation processes. Jupiter has the remarkable feature of being uniformly enriched in various elements compared to the Sun,…
