Polycyclic aromatic hydrocarbons (PAHs) are small molecules consisting of rings of carbons, ubiquitous in the interstellar medium. However, PAHs do not seem to be present in protoplanetary disks around the youngest stars. Today’s paper tries to understand why that is.
Planets should form aligned with their host protoplanetary discs. So why does this star have a planet and disc that aren’t at all in line?
The discovery of the planet LHS 3154b outside of our solar system suggests that state-of-the-art models of planet formation are flawed.
This bite reports a serendipitous discovery of what is possibly the largest protoplanetary disk, which has an interesting shape.
Tracking disk chemistry is complicated. Can machine learning make it easier?
Aside from their name, warped astrophysical disks have little in common with the warp drive. Nonetheless, come and enjoy a journey exploring them in today’s bite!
