New classical Cepheids in the inner part of the northern Galactic disk
  and their kinematics
  The characteristics of the inner Galaxy remain obscured by significant dust
extinction, and hence infrared surveys are useful to find young Cepheids whose
distances and ages can be accurately determined. A near-infrared photometric
and spectroscopic survey was carried out and three classical Cepheids were
unveiled in the inner disk, around 20 and 30 degrees in Galactic longitude. The
targets feature small Galactocentric distances, 3-5 kpc, and their velocities
are important as they may be under the environmental influence of the Galactic
bar. While one of the Cepheids has radial velocity consistent with the Galactic
rotation, the other two are moving significantly slower. We also compare their
kinematics with that of high-mass star-forming regions with parallactic
distances measured.
