Asymptotic Giant Branch Stars in the Nearby Dwarf Galaxy Leo P (2019)
Journal Article
Van Loon. (2019). Asymptotic Giant Branch Stars in the Nearby Dwarf Galaxy Leo P. Astrophysical Journal, https://doi.org/10.3847/1538-4357/ab418a

We have conducted a highly sensitive census of the evolved-star population in the metal-poor dwarf galaxy Leo P and detected four asymptotic giant branch (AGB) star candidates.

A three-dimensional map of the hot Local Bubble using diffuse interstellar bands (2019)
Journal Article
Van Loon. (2019). A three-dimensional map of the hot Local Bubble using diffuse interstellar bands. Nature Astronomy, 922 - 927. https://doi.org/10.1038/s41550-019-0814-z

The Solar System is located within a low-density cavity known as the Local Bubble1–3, which appears to be filled with an X-ray-emitting gas at a temperature of 106?K (ref. 4). Such conditions are too harsh for typical interstellar atoms and molecules... Read More about A three-dimensional map of the hot Local Bubble using diffuse interstellar bands.
