Request for a spectrum of TYC 4246-883-1

Post by Francois Teyssier »

A professionnal team has recently established (photometry) that TYC 4246-883-1 is a delta scuti star.

A spectrum of the object is requested. LISA, DADOS-200, Alpy600 will be perfect for that mag V ~ 11 target.

Coordinates:

The spectrum should be published in the discovery paper.

Send it to: francoismathieu.teyssier [] bbox.fr

Woody Sims and Hubert Boussier obtained spectra of the target
The spectral type should be ~F0 with insterstellar redenning ~ 0.2

No more spectra are needed (the spectral variability is expected to be very low)
