The Period and Light Curve of HZ 29 Ostriker, Jeremiah P. ; Hesser, James E. Abstract The periodic variability, discovered by Smak, of the fourteenth-magnitude object HZ 29 has been reinvestigated, using extensive new photoelectric data and modern autocorrelation analytical techniques. The variations, which have maintained a constant phase over at least a quarter of a year, allow us to determine the period to high accuracy: 1051.118 ± 0.015 sec. Combining the observations using this period, we find a mean light curve having an amplitude of about 0.01 mag and the character of a double wave. These observations confirm this star as the shortest-period variable star for which a light curve is available. Although the nature of HZ 29 remains unclear, it seems increasingly unlikely that it is, as suggested by Burbidge, Burbidge, and Hoyle, a quasi-stellar object with large redshift Publication: The Astrophysical Journal Pub Date: September 1968 DOI: 10.1086/180242 Bibcode: 1968ApJ...153L.151O full text sources ADS | data products SIMBAD (3) Related Materials (2) Part 1: 1967ApJ...148L.161L Part 3: 1969ApJ...155..919H
