Smertrios is a metal-rich hot Saturn orbiting HD 149026—a yellow subgiant star of spectral type G0 IV, at a distance of some 248.5 light years. The planet has a radius of about 0.81 Jupiter ...

One study indicates that HD 149026 b—a relatively small but extremely dense planet orbiting a distant star—has an atmospheric temperature of 2,300 kelvins (about 3,700 degrees Fahrenheit), or ...

Yikes! For HD 149026 b to reach such blistering heat, researchers say, it must suck up nearly all the energy it receives from its big bluish star. If so, the gaseous planet could be nearly pitch ...

The exoplanet has been designated the HD 149026 b, which has been dubbed Smertrios. The scientists reported the findings in a research paper which was published on the preprint server arXiv.

Astronomers have detected water vapor in the atmosphere of HD 149026 b, an exoplanet also known as "Smertrios." This discovery may help solve the mystery of the planet's unusual formation.

Astronomers have detected signs of water vapor in the atmosphere of a hot Saturn-type exoplanet, designated HD 149026 b and nicknamed Smertrios, thanks to the CARMENES spectrograph at the Calar Alto ...
