TY - JOUR ID - 1379008 AU - Paunzen, Ernst - Janík, Jan - Kurfürst, Petr - Liška, Jiří - Netopil, Martin - Skarka, Marek - Zejda, Miloslav PY - 2017 TI - Tracing the B[e] Phenomenon with the Narrow-Band delta a Photometric System PB - Astronomical Society of the Pacific CY - San Francisco, USA SN - 9781583819005 KW - photometry KW - delta a photometry KW - B[e] stars KW - Magellanic Clouds N2 - We present a case study and first results of the 3 filter narrow-band delta a photometric system to detect B[e] stars in an efficient way. One filter measures the flux at 5200 A where several Fe II emission lines are located. On the basis of available spectra, we investigated the expected area in the diagnostic tool of the delta a system, the so-called normality line, where these objects are located. They are well separated from all other known non-standard stars in the corresponding Teff (color) region. The first results of our photometric survey in the Magellanic Clouds are very promising and show the high potential of delta a photometry to significantly contribute to this research field. ER -
