We describe designs for practical detectors of absolute rotation, which rely on the creation magnetic fields by charged objects that are rotating with respect to an inertial frame. Our designs, motivated original suggestion R.M. Brady, utilise properties superconductors, both shield and confine fields, also as basis a SQUID detector produced. show commercially available SQUIDs, our can have suf...

In the present work, we study the link between rotation and lithium abundance in giant stars of luminosity class III, on the basis of a large sample of 309 single stars of spectral type F, G and K. We have found a trend for a link between the discontinuity in rotation at the spectral type G0III and the behavior of lithium abundances around the same spectral type. The present work also shows tha...

Spatially resolved velocity profiles are presented for nine faint field galaxies in the redshift range 0.1 ∼ < z ∼ < 1, based on moderate–resolution spectroscopy obtained with the Keck 10 m telescope. These data were augmented with high–resolution Hubble Space Telescope images from WFPC2, which provided V and I photometry, galaxy type, orientation, and inclination. The effects of seeing, slit w...

We have investigated the effects of uniform rotation and a specific model for differential rotation on the pulsation frequencies of 10 M⊙ stellar models. Uniform rotation decreases the frequencies for all modes. Differential rotation does not appear to have a significant effect on the frequencies, except for the most extreme differentially rotating models. In all cases, the large and small sepa...
