Abstract

Starburst features in the optical are nowadays well known, but the use of this knowledge is not always possible (e.g. objects heavily obscured). In this case the near-IR is of unprecedented value. Recent models show that TP-AGB stars should dominate the NIR spectra of populations 0.3 to 2 Gyr old. We propose here to take advantage of the ideal coverage of the IRTF Spex instrumentto create the first empirical database of NIR spectra of carefully selected starburts to test for the first time and in a consistent way the new stellar population models that account for the TP-AGB.
