Spectroscopy and photometry for low-mass stars in Praesepe.

WILLIAMS S.D., STAUFFER J.R., PROSEER C.F. and HERTER T.

Abstract (from CDS):

We have obtained spectral types, H-alpha equivalent widths and optical photometry for a small sample of late K and M dwarf candidate members of the Praesepe open cluster. At least for the small sample of stars we have observed, all of the Praesepe members later than M2 have H-alpha in emission. The chromospheric activity of the Praesepe stars is essentially the same as that for Hyades members of the same mass, as expected since the two clusters are thought to be the same age.
