| Abstract: |
This newly discovered d Scuti star shows 13 frequncies, for which no idenification of the harmonic degrees are available. Spectroscopy was done, but is only accurate enough for deriving (v sin i). The model parameters were constrained from ubvy photometry. We show that stability consideration as well as patterns in the periodogram are useful for further constraining the parameters. An attempt has been made to accurately reproduce the measured frequencies with the model ones considering various mode identifications. A moderate success has been achieved. To reproduce observed frequencies at the level of 10-3, we need to postulate that at least 2 of the excited modes have l greater than 2. |
