Mercury and platinum abundances in mercury-manganese stars
Over the years I have been involved in many areas of research, from millimetre-wave research to astronomy education, to my main field of stellar spectroscopy and elemental abundances. Here is my list of publications of M M Dworetsky which I will gradually link up to the ADS pages when I have time to do this.
Here is an HTML version of an article on the calculation of shadows in Dealey Plaza on 22nd November 1963, which was published in The Dealey Plaza Echo, the journal of the UK research group on the assassination of President John F. Kennedy, Dealey Plaza UK .
Sun Angles in Dealey Plaza during the Assassination of President Kennedy
Many aspects of the photography of these events are controversial or require further study. In this article I use astronomical methods to calculate the best times for photographers to duplicate the precise elevation and bearing (or altitude and azimuth) of the sun at the moment of the shooting of President Kennedy and Governor Connolly at 12.30pm Dallas time on 22 November 1963.
Here is a link to an article I wrote for The Assassination Web , and electronic newsletter, about one of the many questionable points in the book "Case Closed":
