Appraising the Necklace: A post-common-envelope carbon dwarf inside an apparently carbon-poor planetary nebula
The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. We aim...
Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the...
Are ultra-diffuse galaxies structurally similar to low-surface-brightness galaxies?
A central question regarding ultra-diffuse galaxies (UDGs) is whether they are in a separate category from low-surface-brightness (LSB) galaxies, or just their...
Asteroid reflectance spectra from Gaia DR3: Near-UV in primitive asteroids
Asteroids are the remnants of the planetary formation in the Solar System and so, their study helps us to understand the conditions during the early stages of...
