Ti I lines at 2.2 m as probes of the cool parts of sunspots
H. N. Smitha, J. S. Castellanos Durán, S. K. Solanki +1
The sunspot umbra harbors the coolest plasma on the solar surface due to the presence of strong magnetic fields. The routinely used atomic lines to observe the photosphere have wea…
Ground-based photometric survey to search for the pulsational variability in Bp, Ap, and Am stars
Daniel Nhlapo, Santosh Joshi, Bruno Letarte +2
We present the analysis of time-series of photoelectric data of a Bp star and four new Ap stars observed photoelectrically under the Nainital-Cape survey programme. The project was…
Photometry of the Scuti star HD 40372
Sukanta Deb, S. K. Tiwari, Harinder P. Singh +2
We present B band photometry of the Scuti star HD 40372 using the ARIES three channel fast photometer attached to the 104-cm Sampurnanand telescope in high-speed photometric mo…
Time-resolved photometric and spectroscopic analysis of a luminous Ap star HD103498
S. Joshi, T. Ryabchikova, O. Kochukhov +4
We present the results on the photometric and spectroscopic monitoring of a luminous Ap star HD103498. The time-series photometric observations were carried out on 17 nights using…
The Nainital-Cape Survey-III : A Search for Pulsational Variability in Chemically Peculiar Stars
S. Joshi, D. L. Mary, N. K. Chakradhari +2
The Nainital-Cape survey is a dedicated research programme to search and study pulsational variability in chemically peculiar stars in the Northern Hemisphere. The aim of the surve…
