Elemental composition is an essential factor in the chemistry of planetary and brown dwarf atmospheres; however, the majority of low-temperature objects near the Sun have nearly indistinguishable abundance patterns. In this talk, I will review some of the key findings of the JWST Cycle 3 "Arcana of the Ancients" program, which obtained NIRSpec and

We report a rotational light curve and Fourier baseline model for the Jupiter Trojan (15094) Polymele, a primary target of the NASA Lucy mission, obtained on 2026 May 19─20 and May 21─22 UT with the Two-meter Twin Telescope (TTT). Phase-Dispersion Minimization over the combined two-night dataset yields P rot = 5.762 ± 0.051 hr and a peak-to-peak

While the influence of supermassive black hole (SMBH) activity on habitability has garnered attention, the specific effects of active galactic nuclei (AGN) winds, particularly ultrafast outflows (UFOs), on planetary atmospheres remain largely unexplored. This study aims to fill this gap by investigating the relationship between SMBH mass at the
