  This work presents the first ever broadband (0.7-25.0 keV) timing and
spectral analysis of Be-HMXB 2S 1417-624 during its 2021 outburst. Using
AstroSat observations, coherent pulsations at ~17.36633 s (MJD 59239.082) were
detected in 0.7-7.0 keV SXT and 3.0-25.0 keV LAXPC data. The pulse profile was
dual peaked at all energies, with the relative intensity of main peak
increasing with energy. The peaks in the SXT profiles were broad and comprised
of several mini-structures. The LAXPC profiles were relatively smooth and had
higher pulsed fraction which increased with energy. The SXT+LAXPC simultaneous
energy spectrum is well described by an absorbed power-law with exponential
cut-off, along with ~1.6 keV black body component and 6.47 keV emission line. A
model comprising of an absorbed power law with high energy cutoff plus a
partial covering absorber and Gaussian emission line also fits the spectrum
quite well. These results have been compared with timing and spectral features
during the previous outbursts of this transient pulsar.
