The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry
Astronomische Nachrichten, EarlyView.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019. These fields were observed between 21 and 407 times sim r′$$ {r}^{\prime } $$ultaneously in (8mag≲r′≲18mag$$ 8\kern0.6em \mathrm{mag}\lesssim {r}^{\prime}\lesssim 18\kern0.6em ...

There is a long-standing discussion in the astrophysical/astrochemical community as to the structure and morphology of dust grains in various astrophysical environments (e.g., interstellar clouds, protostellar envelopes, protoplanetary and debris disks ...

Meteoritics &Planetary Science, EarlyView.Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Astrophysical dust formation under the influence of temperature fluctuations
, 2008 Context. Dust formation, i.e. the condensation of solid particles from a gas phase, occurs in astrophysical environments that are sufficiently cool and offer a sufficiently high density of condensable species.

The Astrophysical Journal, 2023 We investigated dusty and dust-free gas dynamics for a radiation-driven sub-parsec-scale outflow in an active galactic nucleus (AGN) associated with a supermassive black hole 10 ^7 M _⊙ and bolometric luminosity 10 ^44 erg s ^−1 based on the two ...

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids
Meteoritics &Planetary Science, EarlyView.Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

[Petrological Analysis of Astrophysical Dust Analog Evolution] [PDF]
, 1997 This project "Petrological analysis of astrophysical dust analog evolution" was initiated to try to understand the vapor phase condensation, and the nature of the reaction products, in circumstellar environments, such as the solar nebula 4,500 Myrs ago ...
