Non-LTE atmosphere models of very luminous sources and their applicability to Little Red Dots, quasi-stars, and similar objects
Fabrice Martins, Daniel Schaerer, Rui Marques-Chaves
We investigate whether atmosphere models traditionally used for massive stars with strong winds can produce synthetic spectra morphologically similar to those of Little Red Dots (L…

Very massive stars at low metallicity: evolution, synthetic spectroscopy, and impact on the integrated light of starbursts
F. Martins, A. Palacios, D. Schaerer +1
We study the spectroscopic appearance of very massive stars and their effect on the integrated light of starbursts at low metallicity (Z). We adopt two frameworks for the mass loss…
