I was asked what the most critical component of successful astronomy research was. My immediate response: “Colleagues who do what they agreed to do, in the time frame they said they would do it in. Treasure them dearly and reciprocate.” beat Them: “…that’s it?” Me: “Pretty much!” 🔭🪐 #astrodon

“Life in the Slow Lane: A Search for Long Term Variability in ASAS-SN” - Petz and Kochanek show the power of all sky surveys over many years - some absolutely fascinating behaviour in these light curves, from dust generation to curious eclipsing systems. 🔭🪐 #astrodon https://arxiv.org/abs/2501.14058

Not all those who wander are lost: Bhaskar and Perets on “Properties of Free Floating Planets Ejected through Planet-Planet Scattering” showing that 40-80% of planets are ejected (with small velocities), and that systems initially starting with 5-10 planets per star (some of which are then scattered out) can match the free floating planet population 🔭🪐 #astrodon https://arxiv.org/abs/2501.13166

A summary of the DASCH project culminating in the DR7: Williams on “DASCH: Bringing 100+ Years of Photographic Data into the 21st Century and Beyond” - this project has brought online photographic plate photometry spanning over 100 years. Astounding, brilliant and tough work. 🔭🪐 #astrodon https://arxiv.org/abs/2501.12977

Astonishing - intensity interferometry in your backyard! Mozdzen+ on “Intensity Interferometer Results on Sirius with 0.25 m Telescopes” with consumer Single Photon Avalanche Detectors. I’m genuinely amazed at what can be done - precision timing to hundreds of picoseconds(!) 🔭🪐 #astrodon https://arxiv.org/abs/2501.09894

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 https://arxiv.org/abs/2501.05431

Is there another massive exoplanet in the Beta Pic system? Lacquement+ on “Dynamics of the Beta Pictoris planetary system and possibility of an additional planet” show that the two known planets cannot sculpt the current circumstellar disk, but an additional one (or two) planets can! #astrodon 🔭🪐 https://arxiv.org/abs/2501.03143

Happy Perihelion Day! The Earth’s orbit is slightly elliptical, and today is when the Earth is closest to the Sun. I also had a clear shot of the Dutch/NATO communications bunker near our house, which earned a 500kt nuclear device on Russian bombing maps in case of World War III :) 🔭🪐 #astrodon

I do love a good Cornu spiral! DeForest+ on “A Simplified Theory of External Occulters for Solar Coronagraphs” might work for exoplanet imaging - occulters are simple in concept, but typical numerical approximations we commonly use in astronomy don’t work: this paper looks at new ones. 🔭🪐 #astrodon https://arxiv.org/abs/2412.21047

Happy Arbitrary Time Change Day! May you have good times with friends and family in the next 31 and a half million seconds :)

After spending a week in England under a permanent fog layer, flying back yesterday and seeing the sun as we broke through the cloud deck was “Trinity seeing the Sun for the first time” levels of epic.

One of the graduate students I work with had access to my office whilst I was away, and I have been discovering photos of me hidden around my office. Apparently I haven’t even found half of them yet… they have been very creative in the hiding spots!

The tilt of the bulge is the thing: Poon et al. on “A potential exomoon from the predicted planet obliquity of β Pictoris b” showing that if upcoming JWST observations confirm a suspected obliquity then there may be a massive exomoon to detect! Keep calm and carry on observing…. 🔭🪐 #astrodon https://arxiv.org/abs/2412.05988

Wow, imagine how differently astronomy would have developed if you had planets orbiting in completely different planes in the sky… Yu+ on “A possible misaligned orbit for the young planet AU Mic c” and the coincidence that we see BOTH transits is astonishing. The Universe is weird. 🔭🪐 #astrodon https://arxiv.org/abs/2411.16958

Merc and Boffin show an "Unequivocal detection of the tidal deformation of a red giant in a binary system via interferometry" with reconstruction from PIONIER fringes - their Roche-lobe filling model fits better than a symmetric model. An amazing result! 🔭🪐 #astrodon https://arxiv.org/abs/2411.14621
