We have a new paper out today diving into the architectural facets unique to Hot Jupiter systems:

Hot Jupiters Have Giant Companions: Evidence for Coplanar High-Eccentricity Migration

My new paper is on arxiv! We surveyed ~110K stars and found a metallicity "cliff" in super-Earth formation. This one has been in the works for a while. Check it out here: https://t.co/9tAx5n0W6d

Yesterday was my last official day as a professional astronomer. It’s been a good run and I have made amazing friendships along the way. Looking forward to the next chapter of my career at Google.

Don’t sleep on this result! We have put a pretty important constraint on the timescale for sub-Neptune mass-loss (about 700 Myr).

@AlexNeedsSpace I don’t know of a formal function for magnitude. But, I highly doubt we are anywhere near that complete with TESS. Maybe for >4 Earth radius and V< 9, completeness might be close to unity.

@astrobites Also @astrobalmer deserves a shoutout here.

[Jon Zink @jonKzink]

I am truly honored to see some of my work featured in a @astrobites article. Thanks for the wonderful write-up.

Putting all of these features together we favor coplanar high-eccentricity migration ---which predicted a >3X mass correlation for HJ outer companions--- as the dominant mechanism for hot Jupiter formation.

🌟Characteristic 3: Eccentricity Unveils Secrets🌟 In Hot Jupiter (HJ) systems, outer companions tend to have mid-range eccentricities, while comparable non-HJ outer companions appear more circular. This suggest a rich dynamic history between HJs and their outer companions.

@sharonxuesong Look out for a very relevant paper on just this topic hitting ArXiv this week 😉.

[ARCHIVED NASA Exoplanets @NASAExoplanets]

Stars that travel high above the galactic plane, shown here in many wavelengths, may have fewer small, hot planets than those nearer the plane, according to a new study. Planet formation might differ from one galactic neighborhood to the next! https://t.co/mXXq8TKLlH

Discovery Alert! 📣
A meticulous study finds that stars on the fringes of the Milky Way possess fewer of the most common planet types. Planet formation – and the resulting families of planets – might differ from one galactic neighborhood to the next! https://t.co/mXXq8TKdw9

[Jon Zink @jonKzink]

I am looking to do some talks this fall about exoplanets and their interactions with galaxy itself.

If you run a colloquium/coffee/group-meeting and are interested please email or DM me.

[Jon Zink @jonKzink]

Apparently people are having trouble with the DMs. Just email me.

I would love to chat/coffee/lunch with #Sagan2023 folks tomorrow (Wednesday). Reach out if you're interested.
