The Age-Rotation-Activity Relation: From Myrs to Gyrs

  journal={arXiv: Solar and Stellar Astrophysics},
Over the past 40 years, observational surveys have established the existence of a tight relationship between a star's age, rotation period, and magnetic activity. This age-rotation-activity relation documents the interplay between a star's magnetic dynamo and angular momentum evolution, and provides a valuable age estimator for isolated field stars. While the age-rotation-activity relation has been studied extensively in clusters younger than 500 Myr, empirically measured rotation periods are…

Magnetic fields on young, solar-type stars
This thesis describes an investigation aimed at using spectropolarimetric observations of the magnetic fields of young solar-type stars to improve the understanding of the early development of solar
Is it possible to detect planets around young active G and K dwarfs
Theoretical predictions suggest that the distribution of planets in very young stars could be very different to that typically observed in Gyr old systems that are the current focus of radial
A Serendipitous Pulsar Discovery in a Search for a Companion to a Low-mass White Dwarf
We report the discovery of a previously unidentified pulsar as part of a radio campaign to identify neutron star companions to low-mass white dwarfs (LMWDs) using the Robert C.\ Byrd Green Bank


The age-activity-rotation relationship in solar-type stars
We present Ca II K line chromospheric fluxes measured from high-resolution spectra in 35 G dwarf stars of 5 open clusters to determine the age-activity-rotation relationship from the young Hyades and
Rotational Velocities of Low-mass Stars in the Pleiades and Hyades (CD-ROM Directory: contribs/terndrup)
We have obtained high-resolution spectra of 89 M dwarf members of the Pleiades and Hyades and have derived radial velocities, Hα equivalent widths, and spectroscopic rotational velocities for these
The Monitor project: rotation of low-mass stars in the open cluster NGC 2547
We report on the results of an i-band time-series photometric survey of NGC2516 using the Cerro Tololo Inter-American Observatory (CTIO) 4-m Blanco telescope and 8k Mosaic-II detector, achieving
A Survey of Chromospheric Activity in the Solar-Type Stars in the Open Cluster M67*
We present the results of a spectroscopic survey of the Ca II H and K core strengths in a sample of 60 solar-type stars that are members of the solar-age and solar-metallicity open cluster M67. We
The Sloan Digital Sky Survey View of the Palomar-Green Bright Quasar Survey
We investigate the extent to which the Palomar-Green (PG) Bright Quasar Survey (BQS) is complete and representative of the general quasar population by comparing it with imaging and spectroscopy from
Low-Mass Dwarf Template Spectra from the Sloan Digital Sky Survey
We present template spectra of low-mass (M0-L0) dwarfs derived from over 4000 Sloan Digital Sky Survey spectra. These composite spectra are suitable for use as medium-resolution (R ~ 1800) radial
