Synthetic M dwarf Spectra

Here you can download PHOENIX BT-Settl synthetic spectra I have generated for my research. For more information about theses models see Allard et al. (2012a) and Allard et al. (2012b). Larger, more general grids are available on France Allard's website.

C and O Grid - Veyette et al. 2016

Below is a table of synthetic M dwarf spectra with varied C and O abundances for Teff = 3000 K and 3500 K models. Models with varied overall metallicty as well are available for Teff = 3000 K models only. For more information about the models, see Veyette et al. (2016).

The files are archived ascii files with two columns. The first column is wavelength in Ångströms. The second column is the base-10 log of the emergent flux in erg s-1 cm-2 Å-1. Download "full_C_and_O_grid.tar.gz" to download all files at once.

The naming convention is:
lte Teff - log(g) -M [M/H] -A [α/M] -C [C/M] -O [O/M] .BT-Settl.txt
Teff is the effective temperature in K.
log(g) is the surface gravity.
[M/H] is the overall metallicity.
[α/M] is the abundance of alpha elements relative to the overall metallicity.
[C/M] is the abundance of carbon relative to the overall metallicity (log(εC) = 8.43 for solar).
[O/M] is the abundance of oxygen relative to the overall metallicity (log(εO) = 8.69 for solar).
