Kodaikanal Solar Observatory (KoSO) possesses one of world’s longest and homogeneous records of sunspot observations that span more than a century (1904–2017). Interestingly, these observations (originally recorded ...
Vibration rotation bands of SiO in sunspots

Gaur, V. P.; Pande, M. C.; Tripathi, B. M. (1978)

The equivalent widths of P(51) and R(43) lines of the 1-0 and P(45) and R(56) lines of the 2-1 vibration rotation bands of SiO near 8 µm region, have computed for Zwaan's(1974) sunspots model at the centre of the disc. The ...
