The B-Index as a Diagnostic of Cool Stars: Assessing Metallicity Dependence of TiO Absorption in the Visible Spectrum

Fatemeh Azizi, Mohammad Taghi Mirtorabi, Zahra Mohammadian

Molecular absorption features constitute essential diagnostics of late-type stellar atmospheres, with titanium oxide (TiO) bands serving as sensitive tracers of effective temperatu…

Titanium Oxide Absorption as a Proxy to Detect Long term Variation and Activity Cycle in Proxima Centauri

Fatemeh Azizi, Mohammad Taghi Mirtorabi, Rahimeh Foroughi

Stellar activity cycles on magnetically active stars can be estimated by molecular absorption bands. We have previously introduced a molecular index which compares absorptional lin…

A survey of TiOλ567 nm absorption in solar-type stars

Fatemeh Azizi, Mohammad Taghi Mirtorabi

Molecular absorption bands are estimators of stellar activity and spot cycles on magnetically active stars. We have previously introduced a new color index that compare absorption…

A New Titanium Oxide Index in Visual Band

Bahar Bidaran, Mohammad Taghi Mirtorabi, Fatemeh Azizi

We introduce a new color index consisting of two spectral band width to measure TiO absorption band strength centered at 567 nm. Based on the most up-to-date line list for TiO we r…

An Updated Wing TiO Sensitive Index for Classification of M-Type Stars

F. Azizi, M. T. Mirtorabi

By careful searching of synthetic and observed spectra in a sample of cool giant and supergiant stars, we have updated the continuum band-passes of near-infrared Wing three filter…
