The Nainital-Cape Survey-IV
Santosh Joshi, P. Martinez, Sowgata Chowdhury +6
The Nainital-Cape survey is a dedicated ongoing survey programme to search for and study pulsational variability in chemically peculiar (CP) stars to understand their internal stru…
Photo-dynamical mass determination of the multi-planetary system K2-19
S. C. C. Barros, J. M. Almenara, O. Demangeon +32
K2-19 is the second multi-planetary system discovered with K2 observations. The system is composed of two Neptune size planets close to the 3:2 mean-motion resonance. To better cha…
A spectroscopic analysis of the chemically peculiar star HD207561
S. Joshi, E. Semenko, P. Martinez +7
In this paper we present a high-resolution spectroscopic analysis of the chemically peculiar star HD207561. During a survey programme to search for new roAp stars in the Northern h…
Discovery of 17 new sharp-lined Ap stars with magnetically resolved lines
L. M. Freyhammer, V. G. Elkin, D. W. Kurtz +2
Chemically peculiar A stars (Ap) are extreme examples of the interaction of atomic element diffusion processes with magnetic fields in stellar atmospheres. The rapidly oscillating…
The Nainital-Cape Survey -- II:Report for pulsation in five chemically peculiar A-type stars and presentation of 140 null results
Santosh Joshi, D. L. Mary, Peter Martinez +5
To search photometric variability in chemically peculiar A type stars in the northern hemisphere. High-speed photometric observations of Ap and Am star candidates have been carried…
The rapidly oscillating Ap star HD 99563 and its distorted dipole pulsation mode
G. Handler, W. W. Weiss, R. R. Shobbrook +9
We undertook a time-series photometric multi-site campaign for the rapidly oscillating Ap star HD 99563 and also acquired mean light observations over two seasons. The pulsations o…
