Caught in the Act: Observations of the Double-mode RR Lyrae V338 Boo During the Disappearance of a Pulsation Mode
Kenneth Carrell, Ronald Wilhelm, Andrew Tom +13
New results on the behavior of the double-mode RR Lyrae V338 Boo are presented. The Transiting Exoplanet Survey Satellite (TESS) observed this star again in 2022, and an observing…
rrlfe: Software for Generating and Applying Metallicity Calibrations for RR Lyrae Variable Stars Across a Wide Range of Phases and Temperatures
Eckhart Spalding, Ronald Wilhelm, Nathan De Lee +7
RR Lyrae stars play a central role in tracing phase-space structures within the Milky Way because they are easy to identify, are relatively luminous, and are found in large numbers…
Modulation of the Blazhko Cycle in LS Her
Ronald Wilhelm, Kenneth Carrell, Hannah H. Means +8
We present analysis of the RR Lyrae star, LS Her and confirm the previously reported modulation to its Blazhko cycles. We performed Fourier analysis on two sectors (Sector 24 & 25)…
The Changing Lightcurve of the Double-Mode RR Lyrae Variable Star V338 Boo
Kenneth Carrell, Ronald Wilhelm, Faith Olsen +3
We present an analysis of the lightcurve extracted from Transiting Exoplanet Survey Satellite Full Frame Images of the double-mode RR Lyrae V338 Boo. We find that the fundamental m…
DA white dwarfs observed in LAMOST pilot survey
Yue-Yang Zhang, Li-Cai Deng, Chao Liu +14
A total of objects from LAMOST pilot survey have been publicly released. In this work, we present a catalog of DA white dwarfs from the entire pilot survey. We outlin…
Hydrogen lines in LAMOST low resolution spectra of RR Lyrae stars
F. Yang, L. Deng, C. Liu +14
The LAMOST spectroscopic survey for Galactic structure and evolution has been in operation since October 2012, following a one-year pilot survey. The pilot survey produced a data r…
