Inclusion of sdBs in evolutionary population synthesis for binary stellar populations and the application: the determination of photo-z and galaxy morphology

Abstract: Subdwarf B stars (sdBs) can significantly change the ultraviolet spectra of populations at age t ∼ 1 Gyr, and have been even included in the evolutionary population synthesis (EPS) models by Han et al. (Mon. Not. R. Astron. Soc. 380:1098, 2007). In this study we present the spectral energy distributions (SEDs) of binary stellar populations (BSPs) by combining the EPS models of Han et al. (Mon. Not. R. Astron.

“…The effect of binaries and stars of higher multiplicities is a complex subject, that can have a significant effect on population synthesis models of galaxies (e.g., Zhang et al 2010;Stanway et al 2016;Conroy 2013). For our current purpose, we must address the fact that the multiplicity factor M F is nearly unity for O-stars, at least in the local universe (e.g., Duchêne & Kraus 2013):…”

“…Yunnan-II stellar population synthesis model (Zhang et al 2004(Zhang et al , 2005(Zhang et al , 2010) is used to model binary evolution in GABE. Yunnan-II is a stellar population synthesis model developed by the Group of Binary Population Synthesis of Yunnan Observatories.…”

“…It is built based on the rapid binary star evolution (BSE) algorithm of Hurley et al (2002), which modeled various binary interactions including mass transfer, mass accretion, common-envelope evolution, collisions, supernova kicks, tidal evolution and angular momentum loss through GWs. In Zhang et al (2010), the evolutionary population synthesis models of Han et al (2007) which considered sub dwarf B stars (sdBs) are also included. With the help of Yunnan-II model, instead of only modeling single star evolution as in Bruzual & Charlot (2003), properties of binary stars in galaxies can be studied.…”

“…Interactions between stars could produce some specific objects, such as blue stragglers (Pols & Marinus 1994) and subdwarf B stars (sdBs, Han et al 2002), both of which would alter the Spectral Energy Distribution (SED) of the entire stellar population significantly. In our model, we introduce binary interactions into galaxy formation and evolution by using the Yunnan-II stellar population synthesis model (Zhang et al 2004(Zhang et al , 2005(Zhang et al , 2010 4 . Yunnan SPSMs are developed by the Group of Binary Population Synthesis, Yunnan Observatories, Chinese Academy of Sciences.…”

“…The Yunnan-II model was constructed for both stellar populations with and without binary interactions by implementing a Monte Carlo simulation and the rapid single and binary stellar evolution (BSE) algorithms (Hurley et al 2000(Hurley et al , 2002. In their latest version of the Yunnan-II model (Zhang et al 2010), the evolutionary population synthesis models of Han et al (2007) which included sdBs were also combined. The Yunnan-III model (Zhang et al 2013) was constructed by employing single stars' evolutionary tracks obtained from the detailed MESA stellar evolution models (Paxton et al 2011).…”
