A perspective from extinct radionuclides on a Young Stellar Object: The Sun and its accretion disk

, 2011
Meteorites, which are remnants of solar system formation, provide a direct glimpse into the dynamics and evolution of a young stellar object (YSO), namely our Sun.

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

Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2676-2702, November 2025.
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.

Deciphering boulder mobility and erosion from cosmogenic nuclide exposure dating [PDF]

, 2013
Large boulders are prominent features in many geomorphic systems and are frequently targeted for cosmogenic exposure dating. Presently, there are little data or theory predicting exposure age, erosion rate, and mobilization frequency of boulders in ...

Dating a Medieval Tsunami With Uranium‐Series Techniques on Caribbean Corals

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Uranium‐series dates from coral boulders constrain the timing of a medieval tsunami from the Puerto Rico Trench. Previously reported evidence for this tsunami includes hundreds of coral boulders that came to rest hundreds of meters inland on Anegada, British Virgin Islands.

Matera: A not so ordinary H5 chondrite breccia with very low density and high porosity

Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2125-2148, September 2025.
Abstract On the evening of February 14, 2023, at 17:58 UT, a fireball was detected by three cameras of the Italian PRISMA network (FRIPON network). The first samples of the Matera meteorite, collected 3 days after the fall, lay on the balcony of a private home.

New experimental limits on the alpha decays of lead isotopes

, 2012
For the first time a PbWO4 crystal was grown using ancient Roman lead and it was run as a cryogenic detector. Thanks to the simultaneous and independent read-out of heat and scintillation light, the detector was able to discriminate beta/gamma ...
