“Hot giants, defined as systems with periods longer than 10 days, are close enough to the star that they have the potential for significant migration.

But not close enough that the effects of the tide can erase the potential traces of that migration. ” Dr. Andres Jordan of the Adolfo Ibáñez University and the Millennium Institute of Astrophysics and its allies.

“Along the same lines, they are far enough away from their original star that their ingenuity has not been inflated by the mechanism used to feed the reds of the hottest giants.”

“But while it is clear that these systems are very interesting, the population of known hot giants around nearby stars (which allows for more detailed characterization) remains very small.”

Called TOI-677b, the new hot giant was detected by NASA’s Exoplanet Inspection Satellite (TESS).

“We follow the host star, TOI-677, which includes several spectrographs to confirm the candidate of the planet in transit TESS and measure its mass,” the astronomers explained.

They discovered that the TOI-677b is approximately 1.2 times larger and more massive than Jupiter.

“Its radius corresponds to what is expected of a gas giant with a core with 10 Earth masses according to the standard model,” he said.

The TOI-677 is an F-type star about 464 light years away from Earth.

Also known as HD 297549 and 2MASS J09362869-5027478, the star is slightly larger and more massive than the Sun and is approximately 2.92 billion years old.

The TOI-677b orbits the star in an eccentric orbit with an orbital period of 11.24 days.

Dr. Jordan and his co-authors stated: “With a singularity of 0.435, it is at the upper limit of eccentricity values for planets with similar periods in the currently known sample.”

An article detailing the discovery will be published in a journal of the American Astronomical Society.
