Stellar Dynamical Models for 797 $z\sim 0.8$ Galaxies from LEGA-C
  We present spatially resolved stellar kinematics for 797 $z=0.6-1$ galaxies
selected from the LEGA-C survey and construct axisymmetric Jeans models to
quantify their dynamical mass and degree of rotational support. The survey is
$K_s$-band selected, irrespective of color or morphological type, and allows
for a first assessment of the stellar dynamical structure of the general $L^*$
galaxy population at large lookback time. Using light profiles from Hubble
Space Telescope imaging as a tracer, our approach corrects for observational
effects (seeing convolution and slit geometry), and uses well-informed priors
on inclination, anisotropy and a non-luminous mass component. Tabulated data
include total mass estimates in a series of spherical apertures (1, 5, and 10
kpc; 1$\times$ and 2$\times$\re), as well as rotational velocities, velocity
dispersions and anisotropy. We show that almost all star-forming galaxies and
$\sim$50\% of quiescent galaxies are rotation-dominated, with deprojected
$V/\sigma\sim1-2$. Revealing the complexity in galaxy evolution, we find that
the most massive star-forming galaxies are among the most rotation-dominated,
and the most massive quiescent galaxies among the least rotation-dominated
galaxies. These measurements set a new benchmark for studying galaxy evolution,
using stellar dynamical structure for galaxies at large lookback time. Together
with the additional information on stellar population properties from the
LEGA-C spectra, the dynamical mass and $V/\sigma$ measurements presented here
create new avenues for studying galaxy evolution at large lookback time.
