  • Search for short-term periodicities in the sun's surface rotation: a revisit 
    Javaraiah, J; Ulrich, R. K; Bertello, L; Boyden, J. E (Springer Netherlands, 2009-06)
    We have used the daily values of the equatorial rotation rate determined from the Mt. Wilson daily Doppler-velocity measurements during the period 3 December 1985 – 5 March 2007 to search for periodicities in the solar ...
  • Signature of extended solar cycles as detected from Ca ii K synoptic maps of Kodaikanal and Mount Wilson Observatory 
    Chatterjee, Subhamoy; Banerjee, D; McIntosh, S.W; Leamon, Robert J; Dikpati, Mausumi; Srivastava, Abhishek K; Bertello, L (IOP Publishing, 2019-03-20)
    In recent years there has been a resurgence of the study of extended solar cycles (ESCs) through observational proxies mainly in extreme ultraviolet. But most of them are limited only to the space-based era covering only ...
  • The solar cycle 
    Javaraiah, J; Rozelot, J. P; Bertello, L (Hindawi Publishing Corporation, 2012-06)
    The Sun provides variable energetic and magnetic field input to the conditions in the heliosphere which directly affect the magnetosphere. In particular, the Sun's variable magnetic fields constitute a rich source for ...
