Photometric Classification of Single and Binary Stars with Mock CSST Observations
The Astronomical JournalIdentifying unresolved binary stars from broadband photometry is important for studies of stellar evolution, binary populations, and Galactic structure, but remains challenging because many single and binary systems occupy overlapping regions of ...

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 ...

An Updated Modular Set of Synthetic Spectral Energy Distributions for Young Stellar Objects
The Astrophysical JournalMeasured properties of young stellar objects (YSOs) are key tools for research into pre-main-sequence stellar evolution. YSO properties are commonly measured by comparing observed radiation to existing grids of template YSO spectral energy distributions (

The State of Astronomy Education in the U.S.
, 1996 I would like to set the scene for the discussion that will follow in this book and bring up a few disturbing points which I believe any discussion about astronomy education will ultimately have to address.

Meteoritics &Planetary Science, EarlyView.Abstract Despite meteorites having been recognized as the source of iron in some ancient iron artifacts, few archeological irons have been analyzed so far, as invasive methods are precluded. In this work, four iron knives and one axe collected near Guelmime and Imilchil (Morocco) were investigated by advanced analytical techniques, including handheld ...

Nondetection of FAST and Parkes Follow-up Observation for 27 Parkes-discovered Fast Radio Bursts
The Astrophysical JournalTo investigate whether apparently nonrepeating fast radio bursts (FRBs) are truly one-off transients, we conducted systematic follow-up observations of 27 out of 81 nonrepeating FRBs identified in the Parkes Transient Database. Using 59.0 hr of data from

Thermal history, collisional history, and structure of the CK‐chondrite parent body
Meteoritics &Planetary Science, EarlyView.Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.
