![]() ![]() and dozens of other projects in North Carolina and around the country. He was the force behind the National Museum of African American History and Culture in Washington D.C. In 2019 architectural giant Phil Freelon died of ALS. Optimize their wavelength regions to deliver both a large variety of elementalĪbundances and reliable age estimates of luminous red giant stars.Nnenna Freelon (left) and Pierce Freelon (right) created the new album "Ancestars." (Chris Charles) This makes it possible for existing and future spectroscopic surveys to We report 215 informative features forĭifferentiating the RC from the RGB within the range of 0.33 to 2.5 microns. With asteroseismic data from the K2 mission confirms that CN, CO and CHįeatures are indeed the primary carriers of spectroscopic information on theĮvolutionary stages of red giant stars. The moderate-resolution VLT/X-shooter spectrograph. These studies to a tenfold larger wavelength range of 0.33 to 2.5 microns with That are still on their first ascent of the red giant branch (RGB). This makes it possible toĬonfidently differentiate core-helium burning red clump stars (RC) from those Separations are imprinted in said spectra. Study of optical and infrared spectra of red giant stars with data-drivenĪnalyses has revealed that differences in oscillation frequencies and their ![]() Giant stars where "gold-standard" asteroseismic data are not available. Banks and 8 other authors Download PDF Abstract: Data-driven analysis methods can help to infer physical properties of red Download a PDF of the paper titled CN and CO Features: Key Indicators of Red Giant Evolutionary Phase in Moderate-Resolution X-Shooter Spectra, by Kirsten A. ![]()
