M giants with IGRINS I. Stellar parameters and -abundance trends of the solar neighborhood population
G. Nandakumar, N. Ryde, L. Casagrande +1
Cool stars, such as M giants, can only be analysed in the near-infrared (NIR) regime due to the ubiquitous TiO features in optical spectra of stars with Teff < 4000 K. In dust obsc…
The Galactic Chemical Evolution of phosphorus observed with IGRINS
G. Nandakumar, N. Ryde, M. Montelius +30
Phosphorus (P) is considered to be one of the key elements for life, making it an important element to look for in the abundance analysis of spectra of stellar systems. Yet, there…
Multiwavelength investigation of extended green object G19.88-0.53: Revealing a protocluster
Namitha Issac, Anandmayee Tej, Tie Liu +5
A multiwavelength analysis of star formation associated with the extended green object, G19.88-0.53 is presented in this paper. With multiple detected radio and millimetre componen…
Temperatures and metallicities of M giants in the galactic Bulge from low-resolution K-band spectra
M. Schultheis, N. Ryde, G. Nandakumar
With the existing and upcoming large multi-fibre low-resolution spectrographs, the question arises how precise stellar parameters such as Teff and [Fe/H] can be obtained from low-r…
