Mapping the Chemodynamics of the Galactic Disk Using the LAMOST and APOGEE Red Clump Stars
The Astrophysical Journal Supplement SeriesA detailed measurement is made of the metallicity distributions, kinematics, and dynamics of the thin and thick disks across a large disk volume (5.0 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc) by using the LAMOST–APOGEE red clump stars.

Astronomische Nachrichten, EarlyView.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

Deuterium toward Two Milky Way Disk Stars: Probing Extended Sight Lines with the Far Ultraviolet Spectroscopic Explorer [PDF]
, 2002 We have carried out an investigation of the abundance of deuterium along two extended sight lines through the interstellar medium (ISM) of the Galactic disk. The data include Far Ultraviolet Spectroscopic Explorer (FUSE) observations of HD 195965 (B1 Ib)

Chemistry &Biodiversity, EarlyView.ABSTRACT This study evaluated the preservative potential of essential oils (EOs) in bakery products by identifying fungal contaminants in bread, testing the in vitro antifungal activity of a mixture of cinnamon, clove, and bay leaf EOs, and assessing their effectiveness in extending shelf life. Fungal identification revealed the presence of Penicillium,

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Wave-corrected Assessment of the Local Midplane
The Astrophysical JournalAs the number of known Galactic structures mounts thanks to the Gaia Space Telescope, it is now pertinent to study methods for disentangling structures occupying the same regions of the Milky Way. Indeed, understanding the precise form of each individual

The Virgo Stellar Overdensity: Mapping the Infall of the Sagittarius Tidal Stream onto the Milky Way Disk [PDF]
, 2006 The recently discovered Virgo stellar overdensity, which extends over ~1000 deg2 perpendicular to the Galactic disk plane (7 kpc < Z < 15 kpc, R ~ 7 kpc), is the largest clump of tidal debris ever detected in the outer halo and is likely related to the ...

On the Formation of Planets in the Milky Way’s Thick Disk
The Astrophysical JournalAbstract Exoplanet demographic surveys have revealed that close-in (≲1 au) small planets orbiting stars in the Milky Way’s thick disk are ∼50% less abundant than those orbiting stars in the Galactic thin disk. One key difference between the two stellar populations is the time at which they emerged: thick-disk stars are the likely product
