Runaway Young Stars near the Orion Nebula [PDF]
Astrophysical Journal, 2019 The star-forming region of the Orion Nebula (ONC) is ideal to study the stellar dynamics of young stars in a clustered environment. Using Gaia DR2 we search for pre-main sequence stars with unusually high proper motions that may be representative of a ...

Soil Science Society of America Journal, Volume 86, Issue 6, Page 1553-1570, November/December 2022., 2022 Abstract In headwater catchments, surface groundwater discharge areas have unique soil biogeochemistry and can be hot spots for solute contribution to streams. Across the northeastern United States, headwater hillslopes with surface groundwater discharge were enriched in soil Mn, including Watershed 3 of Hubbard Brook Experimental Forest, New Hampshire.

A VLBA Survey of Radio Stars in the Orion Nebula Cluster. II. Astrometry [PDF]
, 2020 From Very Long Baseline Array (VLBA) observations we previously identified a population of 123 young stellar systems with nonthermal radio emission toward the core of the Orion Nebula Cluster (ONC).

Approaches to interrogate the erased histories of recycled archaeological objects
Archaeometry, Volume 64, Issue S1, Page 187-205, June 2022., 2022 Abstract Any archaeological artefact made from recyclable material may have been recycled before deposition. Three approaches are presented which have identified recycling in the archaeological record: (1) the application of log ratio analyses to investigate compositional data indicates that Roman glass was recycled and reapplied as a glaze on Parthian

EVOLUTION OF THE CRAB NEBULA RADIO EMISSION
Odessa Astronomical Publications, 2017 In 1977-1992 the flux density of the Crab Nebula in respect to Orion Nebula was measured at the frequency of 927 MHz with the same 10-m radio telescope.

Large Scale Flows from Orion-South [PDF]
, 2007 Multiple optical outflows are known to exist in the vicinity of the active star formation region called Orion-South (Orion-S). We have mapped the velocity of low ionization features in the brightest part of the Orion Nebula, including Orion-S, and imaged

When the tale comes true: multiple populations and wide binaries in the Orion Nebula Cluster [PDF]
Astronomy & Astrophysics, 2019 Context. Recently published high-quality OmegaCAM photometry of the 3 × 3 deg around the Orion Nebula Cluster (ONC) in r, and i filters revealed three well-separated pre-main sequences in the color-magnitude diagram (CMD).

A VLBA Survey of Radio Stars in the Orion Nebula Cluster. I. The Nonthermal Radio Population [PDF]
, 2020 We present first results of a four-epoch VLBA survey for nonthermal emission toward all 556 compact radio sources previously identified in a deep VLA survey of the Orion Nebula Cluster (ONC).

Early solar irradiation as a source of the inner solar system chromium isotopic heterogeneity
Meteoritics &Planetary Science, Volume 56, Issue 11, Page 2083-2102, November 2021., 2021 Abstract Different solar system objects display variable abundances of neutron‐rich isotopes such as 54Cr, 50Ti, and 48Ca, which are commonly attributed to a heterogeneous distribution of presolar grains in different domains of the solar system. Here, we show that the heterogeneity of 54Cr/52Cr and the correlation of 54Cr/52Cr with Fe/Cr in metal ...
