cds-question@unistra.fropen-star-clustersstellar-massesinfrared-photometryvisible-astronomyeffective-temperatureradial-velocitymultiple-starsWe analyze K2 light curves for 132 low-mass (1M_{sun}_>~M*>~0.1M_{sun}_) members of the 600-800Myr old Hyades cluster and measure rotation periods (P_rot_) for 116 of these stars. These include 93 stars with no prior P_rot_ measurements; the total number of Hyads with a known P_rot_ is now 232. We then combine literature binary data with Gaia DR2 photometry and astrometry to select single-star sequences in the Hyades and its roughly coeval Praesepe open cluster and derive a new reddening value of A_V_=0.035+/-0.011 for Praesepe. Comparing the effective temperature-P_rot_ distributions for the Hyades and Praesepe, we find that solar-type Hyads rotate, on average, 0.4d slower than their Praesepe counterparts. This P_rot_ difference indicates that the Hyades is slightly older than Praesepe: we apply a new gyrochronology model tuned with Praesepe and the Sun and find an age difference between the two clusters of 57Myr. However, this P_rot_ difference decreases and eventually disappears for lower-mass stars. This provides further evidence for stalling in the rotational evolution of these stars and highlights the need for more detailed analysis of angular momentum evolution for stars of different masses and ages.2019ApJ...879..100Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/879/100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-2005)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/315 : UCAC3 Catalogue (Zacharias+ 2009)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+A/331/81 : Hyades membership (Perryman+ 1998)J/AJ/121/3224 : Speckle interferometry of HIP binaries (Mason+, 2001)J/ApJS/159/141 : Spectroscopic properties of cool stars.
