Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

The fall of the Haag (LL4‐6) chondrite breccia—Just 8 years after the nearby fall Stubenberg (LL6)

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract On October 24, 2024, an impressive fireball was visible over Austria. After the possible strewn field was calculated, the first sample of the Haag meteorite, with a mass of 8.76 g, was discovered on November 2, 2024, 8 days after the fireball event. Four more samples were found afterward putting the total sample mass at about 151 g.

Sulfide–Metal Assemblages on CR2 Chondrule Rims: Products of Nebular Fission–Sulfidization and Parent Body Oxidation–Serpentinization

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We conducted a scanning electron microscopy (SEM) and transmission electron microscopy (TEM) study of sulfide–metal assemblages (SMAs) in minimally to moderately altered CR2 chondrites. The assemblages occur on chondrule rims and consist of kamacite cores rimmed by pyrrhotite.

First‐Generation Inequalities, Adaptation, and Resilience

open access: yesSociological Forum, EarlyView.
ABSTRACT First‐generation college students face systemic barriers to persistence, including lower campus engagement, delayed graduation, and higher departure rates compared to their continuing‐generation peers. While these disadvantages are well documented, less is known about how first‐generation students adapt to institutional contexts laden with ...
