Happy to share the first paper from the SPACE Program, led by my student Angelique Kahle! she observed a hot little sub-Neptune, HD 86226c (Rp = 2.3 Re; equilibrium temp = 1300 K). arxiv.org/pdf/2507.13439

The spectrum is *really* flat ! here's the amplitude compared to other gaseous planets.

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

Gemini North found a hidden companion star orbiting inside Betelgeuse’s atmosphere, the first close-in companion ever seen around a supergiant star.

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.

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...

Excited to be at Exoclimes (@exoclimes.bsky.social) this week! Come find me at poster 139 🪐

I'm building a retrieval framework to help make sense of variability in brown dwarfs and directly imaged planets.

Come say hi, and we can nerd out about variable atmospheres 😊

Since many people can't make it to Exoclimes, here is my poster looking at the geometry of magnetic drag models in hot Jupiter atmospheres. There are many caveats about the applicability of these models, but they're a first step in including dayside coupling.

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.

Duncan Christie @astroduncan.bsky.social · Jun 24

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.

Introducing...your sneak peek at the cosmos captured by NSF–DOE Vera C. Rubin Observatory!

Can you guess these regions of sky?

This is just a small peek...join us at 11am US EDT for your full First Look at how Rubin will #CaptureTheCosmos! 🔭🧪

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions.

All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.

A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars.

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👇 🔭🧪

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...

Matthew Kenworthy @mattkenworthy.bsky.social · Jan 10

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.
