UW CMa

UW CMa is one of the 'windy massive' OB stars requiring ground based high-res spectroscopy concurrently with high precision photometry from the BRITE-Constellation satellites campaign. A project document is available. Details on BRITE-Constellation's current and future targets are available at the BRITE-Constellation website.

Basic campaign observing information: UW CMa (aka HD57060/29 CMa/HR2781): This V~5.0, O7Ia:fp star is near Sirius. (07 18 40.3, -24 33 32.0, epoch 2000) Spectra of as many key lines as possible in the blue-red optical region (with emphasis on the line-rich blue region between 3800 A and 4900A) is requested but if only a single order is possible then nightly spectra of windows (>150A) centred on the He II lines at 4686 A and 5411 A is preferred. A resolution R~10,000 and SNR of at least 200 is required.

The project PI is Anthony Moffat
