Possible Implications of the Planet Orbiting the Red Horizontal Branch Star HIP 13044
Ealeal Bear, Noam Soker, Amos Harpaz
We propose a scenario to account for the surprising orbital properties of the planet orbiting the metal poor red horizontal branch star HIP 13044. The orbital period of 16.2 days i…
Triggering Eruptive Mass Ejection in Luminous Blue Variables
Amos Harpaz, Noam Soker
We study the runaway mass loss process of major eruptions of luminous blue variables (LBVs) stars, such as the 1837-1856 Great Eruption of Eta Carinae. We follow the evolution of a…
Overluminous Blue Horizontal Branch Stars Formed by Low Mass Companions
Noam Soker, Amos Harpaz
We construct a speculative scenario for rotation-induced extra helium mixing to the envelope of horizontal branch (HB) stars. This scenario differs from previous ones in that the m…
Stellar structure and mass loss during the early post asymptotic giant branch
Noam Soker, Amos Harpaz
Late asymptotic giant branch (AGB) and early post-AGB stars which are progenitors of planetary nebulae lose mass at extremely high rate, in what is termed a superwind. We show that…
Equation of Motion of an Electric Charge
Amos Harpaz, Noam Soker
The appearance of the time derivative of the acceleration in the equation of motion (EOM) of an electric charge is studied. It is shown that when an electric charge is accelerated,…
Criticism of recent calculations of common envelope ejection
Noam Soker, Amos Harpaz
We re-examine a recent claim by Han et al. (2002) that the ionization energy in the envelope has to be included in the ejection criterion of common envelopes. In particular, we arg…
