Recent Minima of 155 Eclipsing Binary Stars
Gerard SamolykPO Box 20939, Greenfield WI 53220
Received March 7, 2008; revised March 26, 2008, accepted March 26, 2008
Abstract The AAVSO’s publication of times of minima for eclipsing binary stars has shifted from the recent publication series, Observed Minima Timings of Eclipsing Binaries, Number 1–12, back to the JAAVSO. Times of minima from observations made in the past eight months are presented. New light elements for AC CMi have been calculated from recent AAVSO observations:
Min(JD) = 2451978.7504 + 0.867216691 E ± 0.0004 ± 0.00000024
1. Background
From 1974 to 1978, the AAVSO Eclipsing Binary Committee published times of minima in the JAAVSO. A large increase in observing activity, starting in the mid-1970s, overwhelmed the manual reduction process in place at that time. During the late 1980s, a computer-aided reduction process was developed and the observations were digitized. By this time there was a large backlog of unpublished times of minima. In Observed Minima Timings of Eclipsing Binaries, Number 1–12, published from 1993 to 2007, almost 15,000 times of minima were published by the committee. As a result of this work, all of the legacy data have been reduced and published. The publication of times of minima has now returned to the JAAVSO. During these years, the method used to observe eclipsing binary stars has changed from almost 100% visual to almost 100% CCD.
2. Recent Observations
The accompanying list contains times of minima calculated from recent CCD observations made by participants in the AAVSO’s eclipsing binary program. This list will be web-archived and available through the AAVSO ftp site at: ftp://ftp.aavso.org/public/datasets/jsamoj362.txt. These observations were reduced by the observers or the writer using the method of Kwee and van Worden (1956). The standard error is included when available. The linear elements in the 1985 General Catalogue of Variable Stars (GCVS; Kholopov et al. 1985) were used to compute the O–C values for most stars. For a few exceptions where the GCVS elements are missing or are in significant error, light elements from another source are used: CD Cam (Baldwin and

Samolyk 2007), CW Cas (Samolyk 1992a), Z Dra (Danielkiewicz-Krośniak and Kurpińska-Winiarska 1996), DF Hya (Samolyk 1992b), EF Ori (Baldwin and Samolyk 2005), GU Ori (Samolyk 1985), IP Peg (Baldwin and Samolyk 2000). O–C values listed in this paper can be directly compared with values published in the Observed Minima Timings series. In the case of AC CMi, the linear elements were calculated by linear regression using the times of minima listed in this publication. The following light elements are used:
Min (JD) = 2451978.7504 + 0.867216691 E (1) ± 0.0004 ± 0.00000024
The number of observations used for determination of each time of minimum is given under N in Table 1 when available. This work is sponsored by the AAVSO, with the writer acting as program coordinator.
