Three-dimensional Reddening Maps of the Magellanic Clouds Constructed by RR Lyrae Stars
The Astronomical JournalWe present the first three-dimensional reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) constructed using fundamental-mode RR Lyrae stars (RRab) from the Optical Gravitational Lensing Experiment (OGLE) survey.

Stellar Atmospheric Parameters of ∼11,000 RR Lyrae Stars from LAMOST Spectra
The Astrophysical Journal Supplement SeriesAccurate determination of the stellar atmospheric parameters of RR Lyrae stars (RRLs) requires short individual exposures of the spectra to mitigate pulsation effects.

Color–Magnitude Diagram of NGC 205 and Its RR Lyrae Variables
The Astronomical JournalWe present the deepest color–magnitude diagram (CMD) for NGC 205 in the F606W (≈ V ) and F814W (≈ I ) filters. Our archival Hubble Space Telescope/Advanced Camera for Surveys field is centered ∼3 $\mathop{.}\limits^{{\rm{^{\prime} }}}$ 8 northwest of the

The Lack of RR Lyrae Variables in Ultrafaint Dwarf Galaxy Sextans II
The Astronomical JournalRR Lyrae in ultrafaint dwarf (UFD) galaxies, if found, would be valuable to constrain the distances of these UFD. In this work, we report our search of RR Lyrae in a recently discovered UFD—Sextans II. Based on multiband (griz) time-series archival DECam

First Detection of Shock Waves in RRc Stars
The Astrophysical JournalAlthough shock waves have been well documented in fundamental-mode RRab stars, their existence in first-overtone pulsator stars, RRc stars, has remained uncertain. Building upon the spectroscopic frameworks established by M. Chadid et al., we present the

Kinematics of Distant Milky Way Halo RR Lyrae Stars out to 160 kpc
The Astrophysical JournalWe present a kinematical study of the outer halo ( r _GC ∼ 60–160 kpc) of the Milky Way (MW) based on spectroscopy of 55 RR Lyrae stars using the Echelle Spectrograph and Imager instrument on the Keck II telescope.
