Detection of atmospheric velocity fields in A-type stars
High signal-to-noise spectra with spectral resolution of more than 105 have been obtained of one normal B9.5V, one normal A1V, two Am stars, and two HgMn B stars having v sin i less than 6 km s−1. These spectra are modeled with LTE line profile synthesis to test the extent to which the spectrum of each star can be modeled correctly with a single set of parameters Te, log g, chemical abundances,...
متن کاملObservational Signatures of the First Stars
At present, there are several feasible observational probes of the first stars in the universe. Here, we examine the constraints on early stellar activity from the metallicity of the high-redshift Ly-α clouds, from the effects of stellar ionizing photons on reionization and the cosmic microwave background (CMB), and from the implications of gravitational microlensing results for the presence of...
متن کاملCircumstellar Disks in pre-Main–Sequence Stars
This review covers the properties of disks around pre-main– sequence stars. It is at this time in the evolution that planets form, and it is important to understand the properties of these disks to understand planet formation. I discuss disk shapes, masses and temperatures, the properties of the host stars, disk lifetimes and dissipation processes. Finally, evidence of grain growth during pre-m...
متن کاملMagnetic flaring in pre-main sequence stars
Observations of nearby star forming clouds with imaging Xray telescopes have revealed that X-ray emission is elevated 10 − 10 above main sequence levels in low-mass pre-main sequence (PMS) stars. The variability and spectral X-ray evidence, together with circularly polarized radio continuum flares seen in a few cases, strongly argues for an origin in magnetic reconnection flares. These high lev...
متن کاملObservational signatures of helical galactic magnetic fields
We investigate the possibility of reproducing the observed polarization and Faraday rotation properties of spiral galaxies assuming their disks to be filled with regular helical magnetic fields. Both small-scale (< 1 kpc) flux tubes predicted by local hydrodynamicmodels and global, galaxy-scale (several kpc) fields generated by the dynamoprocess are considered. The large-scale fields are found ...
