Interesting seminar today by Jonathan Grone, a PhD student at the University of Bern. He discusses how we can use polarisation to detect biosignatures. He also shows how space science is helping with medical science, the same polarisation techniques can detect cancerous tumours!

Congratulations to Dr. Richard Chatterjee, my DPhil student who passed his viva on atmospheric escape today and is off to a position at Leeds. (Me on the left, his examiners Garcia-Muñoz and Tad Komacek on the right -- Tad and Richard are in the traditional subfusc, except should be white tie)

New paper on the climate and habitability of Tergarden’s star b, led by Ryan Boukrouche and ft. Me!
This planet is a promising target for characterisation by next generation observatories such as LIFE.
Take a peak to see what we found out…. (or just read the title 🙃)

Today at #EPSCDPS2025 there is a talk by Oxford PCDgroup alumnus Maxence Lefevre on sulfur allotropes in the Venus atmosphere. 11AM in Room Sun. This is one of many talks and posters on Venus and even Titan Maxence is involved in. Maxence was a postdoc on my ERC EXOCONDENSE project.

Very excited to share that my new paper has been accepted for publication in MNRAS!
We are applying Doppler Imaging to model the activity signals from the HARPS-N Sun-as-a-star spectra! We show that injected planets can be retrieved with great accuracy!

In our now-published paper we model the early history of three exoplanets to specifically study the role of tidal heating on their capacity to solidify. A physically robust feedback mechanism can keep them molten, even with relatively thin atmospheres, which may extend to lots of rocky exoplanets.

Limits on the atmospheric metallicity and aerosols of the sub-Neptune GJ 3090 b from high-resolution CRIRES+ spectroscopy
The sub-Neptune planets have no solar system analogues, and their low bulk densities suggest thick atmospheres containing degenerate quantities of volatiles and H/He, surrounding cores of unknown size...
