This paper not only confirms a new exoplanet, but also helps explain why some M dwarfs host short-period giants while most don't—they may need a distant companion to drive the dramatic orbital migration. Every planet's story is shaped by distant gravitational tugs. 9/9 🔭 🧪 #exoplanet

Jingyuan Zhao (赵经远) @astrozhao.bsky.social · 30/07/2026
This suggests wide companions boost short-period giant planets around M dwarfs. We interpret this via high-eccentricity migration: the companion's gravity makes the planet's orbit highly eccentric; tides at periastron gradually circularize and shrink it, forming a hot Jupiter. 8/9 🔭 🧪 #exoplanet

Jingyuan Zhao (赵经远) @astrozhao.bsky.social · 30/07/2026
The contrast is striking: 34.2% (±9.5%) of the planet-host M dwarfs have at least one wide companion, versus only 5.3% (±3.7%) for the control sample – a difference of ~6.5×. 7/9 🔭 🧪 #exoplanet

Jingyuan Zhao (赵经远) @astrozhao.bsky.social · 30/07/2026
But this paper went further: it searched for wide companions (projected distance 100–10000 AU) in two samples: (1) all M dwarfs hosting short-period giant planets, and (2) a control sample of random field M dwarfs with similar properties. 6/9 🔭 🧪 #exoplanet

I spent almost 2 hours painstakingly copying the orbits of all 128 Saturnian moons from the announcement MPEC and reformatting them for visualization... Behold, here are the orbits of ALL 128 MOONS OF SATURN. This isn't just a moon system—it's a literal asteroid belt around Saturn! 🧪🔭☄️
Saturn's outer moon system viewed from the north pole of Saturn. Moons orbiting in clockwise (retrograde) orbits have red-colored orbits while moons orbiting counterclockwise (prograde; in the direction of Saturn's spin) are colored blue. With so many irregular moons occupying the same region and intersecting each other, the irregular moon system looks like a donut-shaped vortex surrounding Saturn.

Each of the 128 new moons is highlighted in the diagram with a white point representing their location, and a brighter-colored orbit. Previously-known moons of Saturn are included in the diagram, but are colored darker.

The regular moons of Saturn are colored turquoise and the outermost regular moons (Titan, Hyperion, and Iapetus) labeled with their name.

At the lower left corner are scale indicators to help visualize the scale of Saturn's irregular moon system. A small gray circle at the left left corner is shown to represent the diameter of the Earth-Moon orbital distance. A linear scale bar is labeled "10 million km" (6.2 million mi) to give a standard distance.View of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Each moon is labeled with their names in turquioise. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons.Side view of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons.

The irregular moons of Neptune (dark green) are also visible in the background to the right of Saturn. The horizontal red line protruding right of Saturn is the orbit path of Saturn.

In an attempt to characterize the quiescent counterpart, Prof. Shafter et al. obtained a spectrum of the putative quiescent counterpart using the Hobby-Eberly Telescope in Jan. 2023. The spectrum is dominated by a blue giant, which cannot be explained by current models.🔭

Jingyuan Zhao (赵经远) @astrozhao.bsky.social · 10/10/2024
The counterpart of the nova is likely associated with a blue 20.5 mag variable star that displays 14.3 d period. At the distance of M31, absolute magnitude of the putative quiescent counterpart is ∼ −4, given its blue, would be unprecedented for known recurrent nova system.🔭
