Listed are some of my scientific papers that give a wider perspective and/or summarize my general view on some of my research areas.
Negative feedback by jets launched by compact objects
Soker, N., Akashi, M., Gilkis, A., Shlomi, H., Papish, O., Refaelovich, M., & Tsebrenko, D. 2012 (arXiv:1209.0168) The jet feedback mechanism (JFM): from supernovae to clusters of galaxies.
With my former and present students we find similarities in processes by which jets launched by compact objects influence their environment. In many cases there is a negative feedback in the sense that the jets prevent further accretion onto the compact object, hence shutting themselves down. Objects studied include: Planetary nebulae, core collapse supernovae, common envelopes, and clusters of galaxies.
Powering intermediate luminosity optical transients (ILOTs; also called Red Novae)
Soker, N. & Kashi, A. 2012, ApJ, 746, 100 Formation of Bipolar Planetary Nebulae by Intermediate-luminosity Optical Transients.
With my former student Amit Kashi we present our model where many ILOTs are powered by extreme accretion rate onto a main sequence star. In some cases the extreme accretion rate comes from stellar merger, e.g. V838 Mon as suggested by Tylenda, R. & Soker. We argue for connection with the Great Eruption of Eta Carinae, V838 Mon, and some bipolar planetary nebulae. With Ealeal Bear we predict that a process where a planet mergers with a brown dwarf will be detected to be part of this group we term the Optical Transient Stripe (OTS). The OTS is drawn below (click on the image to enlarge it). An updated version with newobjects can be found here.
Planetary nebulae (PN)
De Marco, O., & Soker, N. 2011, PASP, 123, 402, The Role of Planets in Shaping Planetary Nebulae.
With Orsola De Marco we list the percentage of stars that form PNe, and the fraction of PNe that are shaped by planets.
Soker, N. 2010, Magnetic Fields in Cooling Flow Clusters: A Critical View, presented in Galaxy Clusters, 26-30 July 2010, Garching, Germany.
I critically examine the evolution of the name “cooling flow”, and argue that the change of name to “cool core” was damaging. I also present my view on magnetic fields in clusters of galaxies.
Jets from young stellar objects (YSO)
Soker, N. 2010, Highlights of Astronomy, 15, 249, Are jets rotating at the launching? presented in the IAU General Assembly, August 2009.
I argue against some claims for detection of rotating jets in YSOs.
