J/A+A/347/164       HD 59435 Geneva photometry                 (Wade+, 1999)

The Ap spectroscopic binary HD 59435 revisited Wade G., Mathys G., North P. <Astron. Astrophys. 347, 164 (1999)> =1999A&A...347..164W (SIMBAD/NED BibCode)
ADC_Keywords: Stars, Ap ; Photometry, Geneva Keywords: stars: chemically peculiar - stars: magnetic fields - stars: individual: HD 59435 - stars: binaries: spectroscopic - stars: evolution Description: The SB2 binary HD 59435 hosts a yellow giant and a magnetic Ap star, the latter being the secondary (Wade et al., 1996, Cat. J/A+A/314/491) and exhibiting spectral lines resolved into their magnetically-split components. Additional measurements of the magnetic field modulus of the Ap secondary are reported, as well as additional radial velocities for both components and photometric magnitudes and colours in the Geneva system. The magnetic field modulus varies with a period of about 1360 days. For a general description of the Geneva photometric system, see e.g. GCPD/13 Objects: ----------------------------------------- RA (2000) DE Designation(s) ----------------------------------------- 07 29 35.41 -09 15 33.8 HD 59435 ----------------------------------------- File Summary:
