Modeling Total Solar Irradiance Variations Using Automated Classification Software On Mount Wilson Data

Autor: Ulrich, R. K., Parker, D., Bertello, L., Boyden, J.

We present results using the AutoClass analysis application available at NASA/Ames Intelligent Systems Div. (2002) which is a Bayesian, finite mixture model classification system developed by Cheeseman and Stutz (1996). We apply this system to Mount

Search for Short-Term Periodicities in the Sun's Surface Rotation: A Revisit

Autor: Javaraiah, J., Ulrich, R. K., Bertello, L., Boyden, J. E.

The power spectral analyses of the Sun's surface equatorial rotation rate determined from the Mt. Wilson daily Doppler velocity measurements during the period 3 December 1985 to 5 March 2007 suggests the existence of 7.6 year, 2.8 year, 1.47 year, 24

Interpretation of Solar Magnetic Field Strength Observations

Autor: Ulrich, R. K., Bertello, L., Boyden, J. E., Webster, L.

This study based on longitudinal Zeeman effect magnetograms and spectral line scans investigates the dependence of solar surface magnetic fields on the spectral line used and the way the line is sampled in order to estimate the magnetic flux emerging
