A companion star …. Inside Betelgeuse’s atmosphere…. You think you know some stuff about the Universe but there’s always more surprises! 🙃🔭✨

From @noirlabastro.bsky.social: Astronomers using Gemini North found a hidden companion star orbiting inside Betelgeuse’s atmosphere, the first close-in companion ever seen around a supergiant star. 🔗 noirlab.edu/public/news/... 📷GeminiObs/NOIRLab/NSF/AURA #astronomy

My paper with Tom Evans-Soma and Nathan Mayne on magnetic drag models is now accepted and up on the arXiv. For a quick summary, look at the PDF of my Exoclimes poster that I shared last week. www.arxiv.org/abs/2507.08511

Geometric Considerations in Hot Jupiter Magnetic Drag Models

Magnetic fields are expected to impact the atmospheric dynamics of hot and ultra-hot Jupiters due to their increased ionization fractions, compared to that of cooler exoplanets, but our ability to mod...

As I sit at Exoclimes listening to a Zoom talk from the UK, I thought I'd share this again. When choosing where to host international meetings, we need to consider the ability of attendees to get visas in a timely manner.

Visitor visa processing times for Canada, by country where you are applying from: Germany/Austria: 315d UK: 343d Citizens of these countries are visa-exempt, but many researchers who aren't visa-exempt live there. As a Canadian about to head to Canada for a conference, I'm embarrassed.

It's the biggest question there is: are we alone in the Universe? Having the tech to probe the chemical composition of distant planets is 🥳, but as this is just a 3σ result (as likely to be noise as it is likely that today is your birthday) take it with a pinch of salt.👇More on the heated debate👇 🔭🧪

An astonishing headline reporting on new observations from a team led to Nikku Madhusudhan claims they’ve found ‘hints of life’ on a planet orbiting a dwarf star some 124 light years away. What’s going on? (1/n) www.bbc.co.uk/news/article... 🔭 🧪

Chris Lintott @chrislintott.bsky.social · last yr.

At some point we need to have a discussion about the ethics of participation in press releases as scientists. From today’s K2-18b saga, Nikku Madhusudhan in the press release says ‘The signal came through loud and clear’ (1/n)

My new paper with Feng Ding and Jun Yang has been accepted at ApJ: arxiv.org/abs/2504.05233. In this study, we find that lower-tropospheric radiative heating is necessary but not independently sufficient to form the NAIV. Instead, the dynamic heating induced by large-scale subsidence is essential.

Formation of Near-surface Atmospheric Inversion and Surface Inversion in Hothouse Climates

A hothouse climate may develop throughout Earth's history and its warming future and on potentially habitable exoplanets near the inner edge of the habitable zone. Previous studies suggested that near...

After years of sweat and tears, my PhD baby is out of the oven. I currently do not have the energy to write a thread about it. In summary: atmospheric modelling with self-consistent microphysical cloud formation is hard. Don't ignore clouds, model them properly. 🪐🔭👩‍🔬🧪 arxiv.org/abs/2501.05521

The $\texttt{MSG}$ model for cloudy substellar atmospheres: A grid of self-consistent substellar atmosphere models with microphysical cloud formation

State-of-the-art JWST observations are unveiling unprecedented views into the atmospheres of substellar objects in the infrared, further highlighting the importance of clouds. Current forward models s...

After years of waiting for another discovery of these bad boys (because I spent way too much time modelling them), finally another one has been found with TESS!!!!

Hon, Rappaport et al. on “A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star” with an orbital period of 1.27 days, this is a fascinating fourth example of this type of object. The eclipses vary from one orbit to another. 🔭🪐 #astrodon

Several panels showing the brightness of the star as a function of time. The star is blocked by a dust tail which creates a light curve with an initially steep drop, followed by a slow rise back to the normal flux of the star. Each eclipse has a slightly different depth and shape.
