Occurrence and characterization of nanosulfide‐rich regions on asteroid Ryugu: Insights from mackinawite and pyrrhotite

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 1, Page 168-181, January 2026.
Abstract Samples returned from asteroid Ryugu by the Hayabusa2 mission are dominated by fine‐grained matrix material made of phyllosilicates and nanosulfides. Here, we report the mineralogical, textural, and chemical characteristics of nanosulfide‐rich regions identified in Ryugu particles.

Short Term Topological Changes of Coronal Holes Associated with Prominence Eruptions and Subsequent CMEs

open access: yes, 2012
We study the short--term topological changes of equatorial and polar coronal hole (CH) boundaries, such as a variation of their area and disintegration, associated to reconnection with nearby (within 15$^\circ$ distance) quiescent prominence magnetic ...

Evaluation of the disturbance caused by aircraft noise by opinion surveys [PDF]

open access: yes
A survey on the disturbance caused by aircraft noise was evaluated. The use of a questionnaire as a scale rather than considering isolated question responses is seen as more objective. A standardized structure for questionnaires of the opinion surveys on

Mineral Weathering Experiments for Terrestrial Planetary Analogs in a Continuous‐Flow Reactor

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
Understanding the groundwater environments for ancient Mars and other terrestrial bodies is of great interest for evaluating their habitability. Here, we experimentally tested simulated aqueous alterations of two Mars simulants (variants of MGS‐1) using a continuous‐flow packed bed reactor, reacting with three ionic simulated groundwater analog ...

New firm performance and territorial driving forces [PDF]

open access: yes
The article analyses recent approaches on entry and post-entry performance by new firms, with particular focus on its applicability to small manufacturing firms recently borned in Argentina. The analysis is based on a sample of small firms created in the

Does regional development explain international youth mobility? Spatial patterns and global/local determinants of the recent emigration of young Italians [PDF]

open access: yes, 2018
In this essay, we tackle the issue of the international mobility of young Italians in relation to regional disparities. Our intention is to determine if and to what extent a relationship exists between regional development and the international mobility ...

The INTEGRAL/SPI response and the Crab observations [PDF]

open access: yes, 2004
The Crab region was observed several times by INTEGRAL for calibration purposes. This paper aims at underlining the systematic interactions between (i) observations of this reference source, (ii) in-flight calibration of the instrumental response and ...
