Zwicky Transient Facility and Globular Clusters: the gr-Band Period-Luminosity Relations for Mira Variables at Maximum Light and Their Applications to Local Galaxies
Chow-Choong Ngeow, Jia-Yu Ou, Anupam Bhardwaj +3
Based on 14 Miras located in 7 globular clusters, we derived the first gr-band period-luminosity (PL) at maximum light for the large-amplitude Mira variables using the multi-year l…
A Distance Measurement to M33 Using Optical Photometry of Mira Variables
Jia-Yu Ou, Chow-Choong Ngeow, Anupam Bhardwaj +4
We present a systematic analysis to determine and improve the pulsation periods of 1637 known long-period Mira variables in M33 using -band light curves spanning ~year…
Difference of photometric properties between regular and non-regular Miras in the Magellanic Clouds
Jia-Yu Ou, Chow-Choong Ngeow
Mira variables are asymptotic giant branch pulsating stars with long pulsation periods and large amplitudes in optical bands. By applying the random forest algorithm to the I-band…
HO Puppis: Not a Be Star but a Newly Confirmed IW And-Type Star
Chien-De Lee, Jia-Yu Ou, Po-Chieh Yu +19
HO Puppis (HO Pup) was considered as a Be-star candidate based on its gamma-Cassiopeiae-type light curve, but lacked spectroscopic confirmation. Using distance measured from Gaia D…
Multiwavelength Period-Luminosity and Period-Luminosity-Color relations at maximum-light for Mira variables in the Magellanic Clouds
Anupam Bhardwaj, Shashi Kanbur, Shiyuan He +8
We present Period-Luminosity and Period-Luminosity-Color relations at maximum-light for Mira variables in the Magellanic Clouds using time-series data from the Optical Gravitationa…
