cds-question@unistra.frvariable-starshst-photometryinfrared-photometryWe present year-long, near-infrared (NIR) Hubble Space Telescope (HST) WFC3 observations of Mira variables in the water megamaser host galaxy NGC 4258. Miras are asymptotic giant branch variables that can be divided into oxygen- (O-) and carbon- (C-) rich subclasses. Oxygen-rich Miras follow a tight (scatter ~0.14mag) period-luminosity relation (PLR) in the NIR and can be used to measure extragalactic distances. The water megamaser in NGC 4258 gives a geometric distance to the galaxy accurate to 2.6% that can serve to calibrate the Mira PLR. We develop criteria for detecting and classifying O-rich Miras with optical and NIR data as well as NIR data alone. In total, we discover 438 Mira candidates that we classify with high confidence as O-rich. Our most stringent criteria produce a sample of 139 Mira candidates that we use to measure a PLR. We use the OGLE-III sample of O-rich Miras in the Large Magellanic Cloud to obtain a relative distance modulus, {mu}_4258_-{mu}_LMC_=10.95+/-0.01 (statistical) +/-0.06 (systematic) mag, that is statistically consistent with the relative distance determined using Cepheids. These results demonstrate the feasibility of discovering and characterizing Miras using the NIR with the HST and the upcoming James Webb Space Telescope and using those Miras to measure extragalactic distances and determine the Hubble constant.2018ApJ...857...67Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/857/67CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)II/288 : IRSF Magellanic Clouds Point Source Catalog (Kato+ 2007)II/195 : Namelists of variable stars Nos.67-73 (Khopolov+, 1985-97)J/A+AS/13/133 : UBV observations of Mira variables (Koester+, 1974)J/A+AS/120/275 : Mira variables light curves (Alard+ 1996)J/A+AS/146/217 : Library of Spectra (0.5-2.5um) of Cool Stars (Lancon+ 2000)J/A+A/377/945 : Variability and spectra of LMC giants (Cioni+ 2001)J/A+A/384/925 : Compiled cat. of stellar data of Miras (Kharchenko+, 2002)J/A+A/406/51 : ISO long period variables in SMC (Cioni+, 2003)J/ApJ/620/961 : Diameters of Mira stars in JHK' bands (Millan-Gabet+, 2005)J/ApJ/652/1133 : BVI photometry of NGC 4258 Cepheids (Macri+, 2006)J/MNRAS/369/751 : Near-infrared photometry of carbon stars (Whitelock+, 2006)J/ApJ/660/1486 : Variability of LMC semiregular variables (Soszynski+, 2007)J/AJ/136/1242 : LMC long-period variables from MACHO (Fraser+, 2008)J/AcA/58/163 : VI light curves of LMC classical Cepheids (Soszynski+, 2008)J/AcA/58/293 : Type-II and anomalous Cepheids in LMC (Soszynski+, 2008)J/MNRAS/386/313 : IR observations of Mira variables (Whitelock+, 2008)J/A+A/503/913 : Synthetic spectrophot. for C-rich giants (Aringer+, 2009)J/MNRAS/399/1709 : Near-infrared survey of Miras (Matsunaga+, 2009)J/MNRAS/399/2063 : LMC red giants in D sequence (Nicholls+, 2009)J/AcA/59/1 : VI light curves of LMC RR Lyrae stars (Soszynski+, 2009)J/AcA/59/239 : VI LCs of LMC long-period variables (Soszynski+, 2009)J/AcA/59/335 : VI light curves of LMC R CBr stars (Soszynski+, 2009)J/MNRAS/394/795 : AGB stars in Fornax dSph galaxy (Whitelock+, 2009)J/ApJ/715/277 : Insights into the Cepheid distance scale (Bono+, 2010)J/AcA/60/179 : VI LCs of LMC double periodic variables (Poleski+, 2010)J/AcA/60/1 : VI light curves of LMC delta Scuti stars (Poleski+, 2010)J/ApJ/708/717 : Light curve templates of RR Lyrae stars (Sesar+, 2010)J/AcA/61/217 : VI LCs of SMC long-period variables (Soszynski+, 2011)J/AcA/63/21 : VI light curves of Galactic LPVs (Soszynski+, 2013)J/A+A/576/A30 : NIR LC templates for classical Cepheids (Inno+, 2015)J/ApJ/812/31 : Local Star Formation effects on type Ia SNe (Jones+, 2015)J/AJ/149/117 : LMC IR survey.
