Determining the distribution of water throughout the main asteroid belt can inform us about the formation and evolution of the early Solar System. A powerful method for probing water abundance involves the observation and characterization of carbon-rich (C-complex) asteroids in the "3-μm region," which contains the fundamental OH stretching mode

Introduction: Trans-Neptunian Objects (TNOs) harbor materials from the early solar nebula (e.g., Gladman et al. 2008; Tegler et al. 2016). Observations from the NIRSpec instrument onboard the James Webb Space Telescope (JWST) included >50 TNOs during Cycle 1 for the large program "Discovering the Compositions of TNOs" (DiSCo-TNOs; #2418; PI: N

Primitive C-complex asteroids, primarily located in the main asteroid belt, are commonly associated with carbonaceous chondrites (CCs) due to their low geometric albedo (typically pv<10%) and similar spectral shape [e.g. 1]. The presence of hydrated minerals and organics in CCs attests to the accretion of volatiles by their parent body in the early

We present the results of time-resolved photometry, abundance analysis, and Doppler imaging of an Ap star, HD 100357. The TESS photometry revealed rotational modulation with a period of 1.6279247 d. Upon inspecting the residuals after removing the rotational period and its harmonics, we found additional frequencies around 15.8054 d $^{-1}$, which

Context. Stellar carbon abundances are crucial for tracing the star formation history and predicting the near-infrared emission of galaxies. It is still a complex task to derive accurate carbon abundance estimates for a wide variety of stars because it is hard to measure it based on atomic and molecular lines. It therefore remains challenging to

Benchmark brown dwarfs in wide binary systems are crucial for characterizing substellar objects and calibrating atmospheric and evolutionary models. However, brown dwarf benchmarks with subsolar metallicity, very cool temperatures, or suitability for dynamical mass measurements are rare, limiting our understanding across the full range of mass, age
