Understanding the Limitations of Gyrochronology for Old Field Stars [PDF]
Astrophys. J. 871, 39 (2019), 2018 Nearly half a century has passed since the initial indications that stellar rotation slows while chromospheric activity weakens with a power-law dependence on age, the so-called Skumanich relations. Subsequent characterization of the mass-dependence of this behavior up to the age of the Sun led to the advent of gyrochronology, which uses the rotation ...

Is happiness u-shaped in age everywhere? A methodological reconsideration for Europe [PDF]
arXiv, 2021 A recent contribution to research on age and well-being (Blanchflower 2021) found that the impact of age on happiness is "u-shaped" virtually everywhere: happiness declines towards middle age and subsequently rises, in almost all countries. This paper evaluates that finding for European countries, considering whether it is robust to alternative ...
