cds-question@unistra.frspectroscopystellar-spectral-typesvariable-starsgiant-starsinfrared-photometryBased on an extensive spectral study of a photometrically confirmed sample of Mira variables, we find a relationship between the relative Balmer emission-line strengths and spectral temperatures of O-rich Mira stars. The F_H{delta}_/F_H{gamma}_ flux ratio increases from less than unity to five as stars cool down from M0 to M10, which is likely driven by increasing TiO absorption above the deepest shock-emitting regions. We also discuss the relationship between the equivalent widths of the Balmer emission lines and the photometric luminosity phase of our Mira sample stars. Using our 291 Mira spectra as templates for reference, 191 Mira candidates are newly identified from the LAMOST DR4 catalog. We summarize the criteria adopted to select Mira candidates based on emission-line indices and molecular absorption bands. This enlarged spectral sample of Mira variables has the potential to contribute significantly to our knowledge of the optical properties of Mira stars and will facilitate further studies of these late-type, long-period variables.2017ApJS..232...16Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/232/16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2014)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003V/146 : LAMOST DR1 catalogs (Luo+, 2015)V/149 : LAMOST DR2 catalogs (Luo+, 2016)V/153 : LAMOST DR4 (Luo+, 2018)J/A+AS/105/311 : M giants spectra and photometry (Fluks+, 1994)J/ApJS/94/687 : Old stellar populations.
