It has a surface temperature of 4,250 K.[6][7] For comparison, the Sun's surface temperature is 5,772 K. V830 Tauri is a weak-lined T Tauri star, a pre-main sequence star that has a surrounding disc producing emission lines in its spectrum.

[4] It is also classified as a BY Draconis variable, cool stars with starspots and chromospheric activity that vary in brightness as they rotate.

Previously, before the discovery of V830 Tauri b (and a slightly older planet named K2-33b, with an age around 5-10 million years), TW Hya b was discovered and disproven and PTFO 8-8695 b / CVSO 30 b was discovered with an age equally young and an orbit even closer.

[4] The discovery of V830 Tauri b, K2-33b and PTFO 8-8695 b / CVSO 30 b suggests that the formation and migration of close-in giant planets can occur on a timescale of only a few million years.

The new discoveries support planet-disc interactions as the most likely mechanism for efficiently producing young hot Jupiters.
