dc.description.abstract | In 1981, the idea of a superwind that ends the life of cool giant stars was proposed(1). Extreme oxygen-rich giants, OH/IR stars, develop superwinds with the highest mass-loss rates known so far, up to a few 10(-4) solar masses (M-circle dot) per year(2-12), informing our understanding of the maximum mass-loss rate achieved during the asymptotic giant branch (AGB) phase. A conundrum arises whereby the observationally determined duration of the superwind phase is too short for these stars to lose enough mass to become white dwarfs( 2-4,6,8-10). Here we report on the detection of spiral structures around two cornerstone extreme OH/IR stars, OH 26.5 + 0.6 and OH 30.1- 0.7, thereby identifying them as wide binary systems. Hydrodynamic simulations show that the companion's gravitational attraction creates an equatorial density enhancement mimicking a short, extreme superwind phase, thereby solving the decades-old conundrum. This discovery restricts the maximum mass-loss rate of AGB stars to around the singlescattering radiation pressure limit of a few 10(-5)M(circle dot) yr(-1). This has crucial implications for nucleosynthetic yields, planet survival and the wind-driving mechanism. | - |
dc.description.sponsorship | This paper uses the ALMA data ADS/JAO.ALMA2015.1.00054.S, 2016.1.00005.S and 2016.2.00088.S. ALMA is a partnership of ESO (representing its member states), NSF (United States) and NINS (Japan), together with NRC (Canada) and NSC and ASIAA (Taiwan), in cooperation with the Republic of Chile. The Joint ALMA Observatory is operated by ESO, AUI/NRAO and NAOJ. This paper makes use of the CASA data reduction package: https://casa.nrao.edu.CASA is developed by an international consortium of scientists based at the National Radio Astronomical Observatory (NRAO), the European Southern Observatory (ESO), the National Astronomical Observatory of Japan (NAOJ), the CSIRO Australia Telescope National Facility (CSIRO/ATNF) and the Netherlands Institute for Radio Astronomy (ASTRON) under the guidance of NRAO.
