The independence of the mid-infrared RR Lyrae Period-Luminosity relation from metallicity from a study of three globular clusters in the Large Magellanic Cloud
Steve Ardern, Vicky Scowcroft, Stijn Wuyts
RR Lyrae are pulsating variable stars tracing old ( Gyr) stellar populations, and exhibit a strong mid-infrared Period-Luminosity (PL) relation that can be calibrated with kno…
Near-IR CO and CN in classical Cepheids
Scott G. Call, Thomas Griffith, Eric G. Hintz +4
We present medium resolution near-infrared spectral measurements of the carbon monoxide (CO) and the cyano radical (CN) features in 12 Galactic classical Cepheids. The pulsation pe…
Changing CO Bands in Near-IR Spectra of CP Cephei
Scott G. Call, Eric G. Hintz, Steve Ardern +2
We present time-series near-infrared spectra for the classical Cepheid, CP Cephei, from the Astrophysical Research Consortium 3.5-m telescope and near-infrared spectrograph, Triple…
First detection of CO emission from Cepheid Variable stars
S. L. Hamer, S. Ardern, V. Scowcroft
We present IRAM 30~m Telescope observations of the CO(1-0) and CO(2-1) emission lines in a sample of eight Cepheid variable stars. The CO(1-0) line is detected in four of the eight…
The mid-infrared Leavitt Law for Classical Cepheids in the Magellanic Clouds
Abigail H. Chown, Victoria Scowcroft, Stijn Wuyts
The Cepheid Leavitt Law (LL), also known as the Period-Luminosity relation, is a crucial tool for assembling the cosmic distance ladder. By combining data from the OGLE-IV catalogu…
3D maps of the Magellanic Clouds using Classical Cepheids
Abigail H. Chown, Victoria Scowcroft
Variable stars have been used for over one hundred years as probes for determining astronomical distances; these distances can be used to map the three-dimensional (3D) structure o…
