cds-question@unistra.frm-starsspectroscopyline-intensitiesWe study the rotation-activity correlations (RACs) in a sample of stars from spectral type dK4 to dM4. We study RACs using chromospheric data and coronal data. We study the Ca II line surface fluxes-P/sini RACs. We fit the RACs with linear homoscedastic and heteroscedastic regression models. We find that these RACs differ substantially from one spectral sub-type to another. For dM3 and dM4 stars, we find that the RACs cannot be described by a simple model, but instead that there may exist two distinct RAC behaviors for the low-activity and the high-activity stellar sub-samples, respectively. Although these results are preliminary and will need confirmation, the data suggest that these distinct RACs may be associated with different dynamo regimes. We also study R'_HK_ as a function of the Rossby number R_0_. We find (i) for dK4 stars, R'_HK_ as a function of R_0_ agrees well with previous results for F-G-K stars and (ii) in dK6, dM2, dM3, and dM4 stars, at a given R_0_, the values of R'_HK_ lie at a factor of 3, 10, 20, and 90, respectively, below the F-G-K RAC. Our results suggest a significant decrease in the efficiency of the dynamo mechanism(s) as regards chromospheric heating before and at dM3, i.e., before and at the transition to complete convection. We also show that the ratio of coronal heating to chromospheric heating L_X_/L_HK_ increases by a factor of 100 between dK4 and dM4 stars.2017ApJ...837...96Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/837/96CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/pollux : POLLUX database of synthetic stellar spectra (Palacios+ 2010-2015)III/159 : Ca II H and K Measurements Made at MWO (Duncan+ 1991)III/231 : The Tycho-2 Spectral Type Catalog (Wright+, 2003)J/A+A/177/131 : CaII & MgII excess flux density in cool stars (Rutten, 1987)J/ApJS/101/117 : UBVRIJHKLMNQ photometry in Taurus-Auriga (Kenyon+ 1995)J/A+A/327/1039 : Structure and evolution of low-mass stars (Chabrier+ 1997)J/A+A/331/581 : Rotation and activity in field M dwarfs (Delfosse+ 1998)J/A+AS/135/319 : ROSAT data of Nearby Stars (Huensch+ 1999)J/AJ/123/3356 : Palomar/MSU nearby star spectroscopic survey.
