dc.description.abstractNew spectrometric (HERCULES) and ground-based multicolour photometric data on the multiple star V410 Puppis are combined with satellite photometry (HIPPARCOS and TESS), as well as historic astrometric observations. Absolute parameters for V410 Pup Aab are derived: M-Aa = 3.15 +/- 0.10, M-Ab = 1.83 +/- 0.08 (M-circle dot); R-Aa = 2.12 +/- 0.10, R-Ab = 1.52 +/- 0.08 (R-circle dot); a = 6.57 +/- 0.04 R-circle dot; T-Aa = 12500 +/- 1000, T-Ab = 9070 +/- 800(K), and photometric distance 350 +/- 10 (pc). We report the discovery of a low-amplitude SPB variation in the light curve and also indications of an accretion structure around V410 Pup B as well as emission cores in V410 Pup C. We argue that V410 Pup is probably a young formation connected with the Vela 2 OB Association. The combined evidence allows an age in the range 7-25 Myr from comparisons with standard stellar evolution modelling.

dc.description.sponsorshipGenerous allocations of time on the 1m McLennan Telescope and HERCULES spectrograph at the Mt John University Observatory in support of the Southern Binaries Programme have been made available through its TAC and supported by its Director, Dr. K. Pollard and previous Director, Prof. J.B. Hearnshaw. Useful help at the telescope were provided by the MJUO management (N. Frost and previously A. Gilmore & P. Kilmartin). Considerable assistance with the use and development of the HRSP software was given by its author Dr. J. Skuljan. We thank Prof. Tim Bedding (University of Sydney) for his suggestions on the interpretation of the pulsation data and advice. Encouragement and support for this programme has been shown by the School of Chemical & Physical Sciences of the Victoria University of Wellington, as well as the Royal Astronomical Society of New Zealand and its Variable Stars South section (http://www.variablestarssouth.org).The Astronomical Institute acknowledges support from the Czech Academy of Sciences (RVO 67985815). It is a pleasure to express our appreciation of the high-quality and ready availability, via the Mikulski Archive for Space Telescopes (MAST), of data collected by the TESS mission. Funding for the TESS mission is provided by the NASA Explorer Program. This research has made use of the SIMBAD data base, operated at CDS, Strasbourg, France, and of NASA's Astrophysics Data System Bibliographic Services. We thank the University of Queensland for collaboration software, and also the anonymous referee for guidance which improved the final paper.
