Sub-Neptunes obliquities & Marroon-X TOI-1759 RVs

We also derive a true obliquity of {psi}=24{deg}+/-12{deg} making this planet consistent with full alignment albeit to <1{sigma}. With a period of 18.85days and an a/R* of 40, TOI-1759A b is the longest period single sub-Neptune to have a measured obliquity.

It joins a growing number of smaller planets which have had this measurement made and, along with K2-25 b, is the only single, aligned sub-Neptune known to date. We also provide an overview of the emerging distribution of obliquity measurements for planets with R<8R_{Earth}_. We find that these types of planets tend toward alignment, especially the sub-Neptunes and super-Earths, implying a dynamically cool formation history.
