The Age – Activity – Rotation Relationship in Solar – Type Stars . ⋆
Measured from high–resolution spectra, we present Ca II K line chromospheric fluxes in 35 G dwarf stars of 5 open clusters to determine the age–activity–rotation relationship from the young Hyades and Praesepe (0.6 Gyr) to the old M 67 (∼ 4.5 Gyr) through the two intermediate age clusters IC 4651 and NGC 3680 (∼ 1.7 Gyr). The full amplitude of the activity index within a cluster is slightly abo...
متن کاملAn investigation of chromospheric activity spanning the Vaughan – Preston gap : impact on stellar ages . ⋆
Context. Chromospheric activity is widely used as an age indicator for solar–type stars based on the early evidence that there is a smooth evolution from young and active to old and inactive stars. However, this transition may require modification as chromospheric activity is not a viable age indicator for stars older than 1 Gyr Aims. We analysed chromospheric activity in five solar–type stars ...
متن کاملImproved Age Estimation for Solar-type Dwarfs Using Activity-rotation Diagnostics
While the strong anti-correlation between chromospheric activity and age has led to the common use of the Ca II H & K emission index (R HK = LHK/Lbol) as an empirical age estimator for solar type dwarfs, existing activity-age relations produce implausible ages at both high and low activity levels. We have compiled R HK data from the literature for young stellar clusters, richly populating for t...
متن کاملThe chromospheric emission of solar - type stars in the young open clusters IC 2391 and IC 2602
In this paper we present chromospheric emission levels of the solar-type stars in the young open clusters IC 2391 and IC 2602. High resolution spectroscopic data were obtained for over 50 F, G, and K stars from these clusters over several observing campaigns using the University College London Echelle Spectrograph on the 3.9-m Anglo-Australian Telescope. Unlike older clusters, the majority (28/...
متن کاملChromospheric Activity in Metal-Poor Dwarfs
We have obtained echelle spectra with the Hubble Space Telescope (HST) of the MgII 2800 Å region of ten stars whose metallicities range from 1/300 to 1/3 that of the Sun, and whose space velocities suggest a halo or old thick-disk origin. Spectra of all ten show doublepeaked emission in the MgII core, very much like the quiet Sun. A halfdozen apparently non-rotating stars were observed more tha...
متن کاملOn the determination of oxygen abundances in chromospherically active stars
We discuss oxygen abundances derived from [O ] λ6300 and the O triplet in stars spanning a wide range in chromospheric activity level, and show that these two indicators yield increasingly discrepant results with higher chromospheric/coronal activity measures. While the forbidden and permitted lines give fairly consistent results for solar-type disk dwarfs, spuriously high O triplet abunda...
