Automated Extended Aperture Photometry of K2 Variable Stars
نویسندگان
چکیده
Abstract Proper photometric data are challenging to obtain in the K2 mission of Kepler space telescope due strong systematics caused by two-wheel-mode operation. It is especially true for variable stars wherein physical phenomena occur on timescales similar instrumental signals. We originally developed a method with aim extend aperture be able compensate motion which we named Extended Aperture Photometry (EAP). Here present outline automatized version EAP method, an open-source pipeline called autoEAP . compare light curve products other solutions examples chosen from high-amplitude stars. In addition photometry, new detrending based phase dispersion minimization and eliminate long-term signals periodic

Photometry of Variable Stars in the Globular Cluster NGC 6397
Time series BV I photometry is presented for 16 short-period variables located in the central region of the globular cluster NGC 6397. The sample includes 9 newly detected variables. The light curve of cataclysmic variable CV6 shows variability with a period of 0.2356 days. We confirm an earlier reported period of 0.472 days for cataclysmic variable CV1. Phased light curves of both CVs exhibit ...
متن کاملTechniques for Automated High-Precision Photometry of Sun-like Stars
Tennessee State University operates several Automatic Photoelectric Telescopes (APTs) located at Fairborn Observatory in the Patagonia Mountains of southern Arizona. The APTs are dedicated to photometric monitoring programs that would be difficult and expensive to accomplish without the advantages provided by automation. I describe the operation of two of the telescopes (0.75 and 0.80 m APTs) a...
متن کاملLINEAR PULSATION CHARACTERISTICS OF MIRA VARIABLE STARS
The linear adiabatic pulsation-periods of Mira variable stars have been derived. Approximately 2701[1]models were calculated for M = 0.7 MΘ to 2 MΘ stars with radii from 180 RΘ to 340 RΘ and luminosities from 2800 LΘ to 10,000 LΘ. The chemical composition of all models is (X,Z) = (0.7,0.02). From the result of this study, linear relations on Luminosity-Period-Mass relationship and luminosity-pe...
متن کاملUnweighted p-center problem on extended stars
An extended star is a tree which has only one vertex with degree larger than two. The -center problem in a graph asks to find a subset of the vertices of of cardinality such that the maximum weighted distances from to all vertices is minimized. In this paper we consider the -center problem on the unweighted extended stars, and present some properties to find solution.
متن کاملAutomated classification of variable stars for ASAS data
With the advent of surveys generating multi-epoch photometry and their discoveries of large numbers of variable stars, the classification of the obtained times series has to be automated. We have developed a classification algorithm for the periodic variable stars using a Bayesian classifier on a Fourier decomposition of the light curve. This algorithm is applied to ASAS (All Sky Automated Surv...
