Spectroscopic observations of the optical counterpart to the ROSAT Wide Field Camera source RE 1816 + 541 are presented. We find that the counterpart is a chromospherically active, rapidly rotating, dM1-2e star with a

of 61 km s−1. No evide... Read More about RE 1816+541: a northern hemisphere analogue to the low-mass rapid rotator HK Aqr..

BD+22DEG4409 - a Rapidly Rotating Low-Mass Member of the Local Association (1994)
Journal Article
Jeffries, R., Byrne, P., Doyle, J., Anders, G., James, D., & Lanzafame, A. (1994). BD+22DEG4409 - a Rapidly Rotating Low-Mass Member of the Local Association. Monthly Notices of the Royal Astronomical Society, 270(1), 153–172. https://doi.org/10.1093/mnras/270.1.153

We present spectroscopic and photometric observations of BD + 22°4409, a nearby, low-mass star which, on the basis of its Galactic space motions and high EUV-to-bolometric luminosity ratio, has been previously assigned membership of the young kinemat...
