Oct 24, 2024 · HD 100546 b is a gas giant exoplanet that orbits a B-type star. Its mass is 8.5 Jupiters, it takes 249.2 years to complete one orbit of its star, and is 53 AU from its star. Its discovery was announced in 2014.

Despite the uncertainty of the planet's properties, a 2017 study calculated HD 100546 b as a very highly reddened substellar object with a good-fit effective temperature of 2,630 K and a planetary mass and radius of 25MJup and 3.4RJup, making it still one of …

An Optical/Near-infrared Investigation of HD 100546 b with the Gemini Planet Imager and MagAO Rameau et al. 2017 | Reference Overview Confirmation and Characterization of the Protoplanet HD 100546 b—Direct Evidence for Gas Giant Planet Formation at 50 AU

Jul 1, 2015 · These authors used the spectra to infer the effective temperature and surface gravity of HD 100546 and then compared the values to stellar evolutionary tracks to get an age.

Dec 30, 2023 · The surface gravity of HD 100546 b is intricately linked to its mass and radius, both of which are subjects of ongoing investigation. The gravitational force experienced on the surface of the protoplanet is a crucial aspect in understanding its physical characteristics and evolutionary path.

HD 100546 appears to be an unprecedented laboratory to study the formation of multiple gas giant planets empirically. Key words: planet–disk interactions – planets and satellites: detection – planets and satellites: formation – planets

Exoplanet HD 100546 b orbits star HD 100546 that lies 359 light years away from the Sun. It weighs about 985.5 Earth masses and orbits its star further than Earth orbits Sun.

In SpaceEngine, HD 100546 B is so large, oblate enough, and has so little density that the surface gravity is negative in certain areas.

Detailed information about planet HD 100546 b and its parameters. Very large radius estimate likely due to the presence of an extended circumplanetary disk or diffuse dust and gas envelope surrounding the planet. Sissa (2017) provide a greater planetary mass (m = 25 M Jup) and higher temperature (T = 2,630 K) for HD 100546 b.

Considering the suspected existence of an additional planet orbiting at ∼13-14 AU, HD 100546 appears to be an unprecedented laboratory to study the formation of multiple gas giant planets empirically.
