RVs of Teegarden's star
Listed in IVOA Registry (Virtual Observatory)
The two known planets in the planetary system of Teegarden's Star are among the most Earth-like exoplanets currently known.
Description
Revisiting this near-by planetary system with two planets in the habitable zone aims at a more complete census of planets around very low-mass stars. A significant number of new radial velocity measurements from CARMENES, ESPRESSO, MAROON-X, and HPF, as well as photometry from TESS motivated a deeper search for additional planets.
We confirm and refine the orbital parameters of the two know planets Teegarden's Star b and c. We also report the detection of a third planet d with an orbital period of 26.13+/-0.04d and a minimum mass of 0.82+/-0.17M_{sun}_. A signal at 96d is attributed to the stellar rotation period.

The interpretation of a signal at 172d remains open. The TESS data exclude transiting short-period planets down to about half an Earth radius. We compare the planetary system architecture of very low-mass stars.
In the currently known configuration, the planetary system of Teegarden's star is dynamically quite different from that of TRAPPIST-1, which is more compact, but dynamically similar to others like GJ1002.
