Metallicity measurements using atomic lines in M and K dwarf stars
We report the first survey of chemical abundances in M and K dwarf stars using atomic absorption lines in high resolution spectra. We have measured Fe and Ti abundances in 35 M and K dwarf stars using equivalent widths measured from λ/∆λ ≈ 33 000 spectra. Our analysis takes advantage of recent improvements in model atmospheres of low-temperature dwarf stars. The stars have temperatures between ...
متن کاملTwo-dimensional spectral observations of sunspots in chromospheric lines
We present two-dimensional spectral observations of two closely located small sunspots in chromospheric lines. Line asymmetries and shifts are derived for the Ca ii K line in particular. It is found that the majority of Ca ii K profiles show a blue asymmetry. Red asymmetry may also appear, but only in some tiny regions. Some ephemeral blue asymmetry patches are found in the umbrae, which seem t...
متن کاملA Photometric Variability Survey of Field K and M Dwarf Stars with Hatnet
Using light curves from the HATNet survey for transiting extrasolar planets we investigate the optical broad-band photometric variability of a sample of 27, 560 field K and M dwarfs selected by color and proper-motion (V −K & 3.0, μ > 30 mas/yr, plus additional cuts in J −H vs. H −KS and on the reduced proper motion). We apply a variety of variability selection algorithms on the light curves to...
متن کاملSpectral Lines from Rotating Neutron Stars
The line profiles from rotating neutron stars are affected by a number of relativistic processes such as Doppler boosts, strong self-lensing, frame-dragging, and the differential gravitational redshift arising from the stellar oblateness. In this Letter, we calculate line profiles taking into account the first two effects, which is accurate for rotation rates less than the breakup frequency. We...
