Winchcombe: An example of rapid terrestrial alteration of a CM chondrite
Meteoritics &Planetary Science, Volume 59, Issue 5, Page 988-1005, May 2024.Abstract Winchcombe is a CM chondrite that fell in England on February 28, 2021. Its rapid retrieval was well characterized. Within two polished sections of Winchcombe, terrestrial phases were observed. Calcite and calcium sulfates were found in a sample recovered from a field on March 6, 2021, and halite was observed on a sample months after its ...

The bimodal initial mass function in the Orion Nebula Cloud [PDF]
, 2016 Due to its youth, proximity and richness the Orion Nebula Cloud (ONC) is an ideal testbed to obtain a comprehensive view on the Initial Mass Function (IMF) down to the planetary mass regime.

Pre‐Orion Cores in the Trifid Nebula [PDF]
The Astrophysical Journal, 2000 The Trifid nebula is a young HII region undergoing a burst of star formation. In this article, we report on far-infrared and millimeter continuum and line observations of several massive and bright protostellar sources in the vicinity of the exciting star fo the nebula, just behind the ionization front.

Geofluids, Volume 2024, Issue 1, 2024.The Bou Azzer polymetallic Co‐Ni‐As±Au±Ag veins in the Central Anti‐Atlas (Morocco) are significant sulfide ores hosted by Neoproterozoic ophiolites and are associated with felsic intrusive and subvolcanic phases. We report new mineralogical and fluid inclusion data to better understand mineralization’s formation processes and fluid evolution which are

Extreme Radio Flares and Associated X-Ray Variability from Young Stellar Objects in the Orion Nebula Cluster [PDF]
, 2017 Young stellar objects are known to exhibit strong radio variability on timescales of weeks to months, and a few reports have documented extreme radio flares with at least an order of magnitude change in flux density on timescales of hours to days ...

THE POPULATION OF COMPACT RADIO SOURCES IN THE ORION NEBULA CLUSTER [PDF]
, 2016 We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30 hr single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1 GHz bands centered at 4.7 and 7.3 ...

JWST/NIRSpec Observations of Brown Dwarfs in the Orion Nebula Cluster
The Astrophysical JournalWe have used the multiobject mode of the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST) to obtain low-resolution 1–5 μ m spectra of 22 brown dwarf candidates in the Orion Nebula Cluster, which were selected with ...

On the Formation of Runaway Stars BN and x in the Orion Nebula Cluster [PDF]
, 2017 We explore scenarios for the dynamical ejection of stars BN and x from source I in the Kleinmann-Low nebula of the Orion Nebula Cluster (ONC), which is important for being the closest region of massive star formation.
