Abstract:
We examine and quantify how hybrid (e.g., UV+IR) star formation rate
(SFR) estimators and the AFUV-β relation depend on inclination
for disk-dominated galaxies using spectral energy distribution
modeling that utilizes the inclination-dependent attenuation curves
described in Doore+ (2021ApJ...923...26D 2021ApJ...923...26D). We perform this analysis on
a sample of 133 disk-dominated galaxies from the CANDELS fields and
18 disk galaxies from the Spitzer Infrared Nearby Galaxies Survey and
Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel
samples. We find that both the hybrid SFR estimators and the
AFUV-β relation present clear dependencies on inclination. To
quantify this dependence in the hybrid SFR estimators, we derive an
inclination and a far-UV-near-IR color-dependent parametric relation
for converting observed UV and IR luminosities into SFRs. For the
AFUV-β relation, we introduce an inclination-dependent
component that accounts for the majority of the inclination dependence
with the scatter of the relation increasing with inclination. We then
compare both of these inclination-dependent relations to similar
inclination-independent relations found in the literature. From this
comparison, we find that the UV+IR correction factor and AFUV for
our hybrid and AFUV-β relations, respectively, result in a
reduction in the residual scatter of our sample by approximately a
factor of 2. Therefore, we demonstrate that inclination must be
considered in hybrid SFR estimators and the AFUV-β relation to
produce more accurate SFR estimates in disk-dominated galaxies.
