Faint intermediate luminosity optical transients (ILOTs) from engulfing exoplanets on the Hertzsprung gap

Omer Gurevich, Ealeal Bear, Noam Soker

We follow the evolution of four observed exoplanets to the time when the respective parent star of each planet evolves off the main sequence and engulfs its planet to start a commo…

Accretion induced merger leading to core collapse supernovae in old stellar populations

Jessica Braudo, Ealeal Bear, Noam Soker

We examine a triple-star evolution that might lead to core collapse supernovae (CCSNe) in stellar populations that are too old to allow for single or binary evolution to form CCSNe…

A red giant branch common envelope evolution scenario for the exoplanet WD 1856 b

Ariel Merlov, Ealeal Bear, Noam Soker

We propose a common envelope evolution (CEE) scenario where a red giant branch (RGB) star engulfs a planet during its core helium flash to explain the puzzling system WD 1856+534 w…

Rapid expansion of red giant stars during core helium flash by waves propagation to the envelope and implications to exoplanets

Ealeal Bear, Ariel Merlov, Yarden Arad +1

We assume that the strong convection during core helium flash of low mass red giant branch (RBG) stars excite waves that propagate to the envelope, and find that the energy that th…

Parasite common envelope evolution by triple-star systems

Noam Soker, Ealeal Bear

We study a scenario by which a giant wide tertiary star engulfs and forces a tight binary system of a white dwarf (WD) and a main sequence (MS) star to enter a common envelope evol…

The future influence of six exoplanets on the envelope properties of their parent stars on the giant branches

Ivan Rapoport, Ealeal Bear, Noam Soker

We study the evolution of six exoplanetary systems with the stellar evolutionary code MESA and conclude that they will likely spin-up the envelope of their parent stars on the red…
