The progress last year

Upon “Precise Masses and Orbits for Nine Radial Velocity Exoplanets” Google Scholar cites eleven followups... so. Far. Let's look at some.

The later of these like Philipot et al. can enjoy the full DR3 from Gaia STL2 which release, still, is not (yet) a time-series on its own; they must do against Hipparchos like Yiting Li did, or else wait that long wait for DR4. Meanwhile the data for all the nearby stars are only getting longer and better (phnarr).

Thus now HD 83443c: A Highly Eccentric Giant Planet on a 22 yr Orbit probably the most descriptive title we'll see outside isekai manga. b was a hot-Jupiter. In between b and c is nothing Saturn-mass; although exists stability-space for habitable Earth-size planets. To that: the dynamics of b and c suggest much violence and scattering in their pasts, to inspire skepticism of anything left in-between.

Next up is Joshua Winn's solo effort Joint Constraints on Exoplanetary Orbits from Gaia DR3 and Doppler Data. As a solo, he's not recalculated Msini or stellar masses, contenting himself to whinge about nobody else revisiting these stars since their initial tags as planet-bearing: thus HIP 66074 and HD 175167. He flags HD 111232's data overall as pointing to a multiplanet system which equations Winn, likewise, won't trouble himself to solve.

Most annoyingly Winn doesn't tell us semimajors. That would require accurate marks on those masses. I mean, sure: HD 111232 as multibody is arguably nonKeplerian but, how about those others? Winn does give us Kepler's equations including this one, I suppose so we can serve ourselves.

So, per Winn: BD-17 0063 (HIP 2247) is a K dwarf at a distance of 35 pc... star's mass to be 0.74 ± 0.04 M_⊙ (the value adopted [by Winn] here) and reported the planet's minimum mass, period, and eccentricity to be 5.1 Jupiter masses, 655.6 days, and 0.54, respectively. Gaia's DR3 points to 81±4° near-edge-on so that true mass is 5.16 M_j. Without running maths I feel this might sweep the HZ.

HD 81040 is near-solar in mass and its Jovian is 7.53 M_j, at maybe 1000 days' orbit so probably at about 2 AU. Similar eccentricity, which looks bad for any 667-day Hilda. HD 132406, even more solar, has a Jovian at about 6 M_j at 900 days. e=2.5 so might allow that Hilda at 605 days.
