UB explains "how this happened"
By Paul Herrick

15:5.8.6. Contractural Stars. In the smaller systems the largest outer planet sometimes draws to
itself its neighboring worlds, while those planets near the sun begin their terminal plunge. With
your solar system, such an end would mean that the four inner planets would be claimed by the
sun, while the major planet, Jupiter, would be greatly enlarged by capturing the remaining worlds.
Such an end of a solar system would result in the production of two adjacent but unequal suns,
one type of double star formation. Such catastrophes are infrequent except out on the fringe of
the superuniverse starry aggregations.


Giant Planet Found Orbiting Tiny Star, And Scientists Say They 'Can't Explain How This Happened'

Dubbed HATS-6b, the newfound gas giant is considered "too big" for its host star, and has a
super-tight orbit. On HATS-6b, one full year lasts a mere 3.3 Earth-days.

"We have found a small star, with a giant planet the size of Jupiter, orbiting very closely," George
Zhou, a Ph.D. student at the Australian National University's Research School of Astrophysics and
Astronomy in Canberra and one of the researchers who discovered the planet, said in a written
statement. "It must have formed further out and migrated in, but our theories can't explain how this
happened."

Planet formation. Astronomers have long believed that planets form out of a swirling disk of gas
and dust around a newborn star. And as Zhou told The Huffington Post in an email, scientists also
think that protoplanetary disks around small stars contain less planet-forming material than the
ones around big stars. That raises an obvious question: since its host star -- an M-dwarf known as
HATS-6 -- is so small, how can HATS-6b be so big?

"The existence of HATS-6b ... presents a challenge to planet formation theories -- any
comprehensive theory of planet formation must explain why gas giants are uncommon around
small stars, but still allow for the occasional formation of these planets," he said in the email.

Starlight dimmed. Zhou and his colleagues discovered the planet after spotting a dip in the
brightness of HATS-6.

Follow-up observations confirmed that the planet's "transit" across the face of the star explained
the dimming and helped astronomers gauge the planet's size. Their research showed that the
radius of the planet is comparable to Jupiter's, and its mass is more similar to that of Saturn.

"We have a series of small telescopes spread around the world -- in Namibia, New South Wales,
and Chile -- we're able to gather continuous observations of objects in the night sky," Zhou told
CNN. "That's how we're discovering these planets."

The research was published online on April 28 in the Astronomical Journal.
