Image of a Newly Formed Planet in a Disk Around a Star

Click For Summary

Discussion Overview

The discussion centers on the visualization of a newly formed planet in a protoplanetary disk around the star PDS 70. Participants explore the implications of the planet's brightness and its classification, as well as the scientific methods used to estimate its characteristics.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants express curiosity about the brightness of the newly formed planet and question whether it might be transitioning into a dwarf star rather than remaining a planet.
  • One participant references an article that discusses a separate study estimating the planet's size, mass, temperature, and orbit, suggesting that it is several times more massive than Jupiter and has a high-temperature atmosphere.
  • Another participant notes the discovery was made by "Keppler," although the context of this statement is not elaborated upon.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of the planet's brightness or its classification, with multiple viewpoints and questions remaining unresolved.

Contextual Notes

The discussion includes references to specific scientific models and estimates, but does not clarify the assumptions or methodologies behind these models, leaving some aspects of the analysis open to interpretation.

A new planet has been visualized in a protoplanetary disk around a star.

It's the bright thing at about 4 o'clock. Star (PDS 70) is blocked out.

Heh. It was discovered by "Keppler".

Amazing, thanks for the pic!

But why is the planet bright? Is it on its way to becoming some sort of dwarf star and perhaps not a planet as such?IH

According to the article:
In another paper published today in Astronomy & Astrophysics, a separate group led by Müller estimated the size, mass, temperature, and orbit of the planet by plugging all the information into various orbital and atmospheric models. The group predicts that PDS 70b is several times more massive than Jupiter, with a cloudy atmosphere that hits temperatures of around 1000°C, despite orbiting its star at roughly the same distance as Uranus from the sun.
