No. How do I do that?

Comments and questions welcome.

So the radius gap may be primordial and photoevaporation, in our view, plays mainly a role of actually filling in the gap region with planets completely or partially stripped of their gas envelope.

This gives these nice 'crocodile' plots where the radius gap is clearly visible out to 0.5 astronomical units (AU) or so.

In our paper we explore instead whether the gap is primordial, so that planets below the gap never accreted gas while planets above the gap did. Gas accretion is triggered in our model when the planets reach pebble isolation mass; the cooling then allows H2/He to be accreted.

The most accepted explanation for this gap is that planets above the gap accreted a thick atmosphere of H2/He from the protoplanetary disc while those below lost this atmosphere by XUV irradiation from the star (these are close-in planets in much warmer orbits than Earth).

The radius valley describes the lack of planets with radii around 1.5-2 times Earth's radius. Here a famous plot of the radius gap from Fulton et al. (2017).

That brings back good memories of my postdoc years in Leiden. Thanks 🙏!
