Role of non-thermal processes in the quiescent and active millimeter spectrum of a young M dwarf
Atul Mohan, Peter H. Hauschildt, Birgit Fuhrmeister +3
Millimeter (mm) emission from F - M dwarfs (cool stars) primarily traces chromospheric activity, with thermal emission thought to dominate in quiescence. Despite the high chromosph…
Limb-Darkening Coefficients for the 4-Term and Power-2 Laws for the JWST Space Mission, Adopting PHOENIX Spherical Models at High Resolution
A. Claret, P. H. Hauschildt, G. Torres
Modeling observations of transiting exoplanets or close binary systems by comparing the observations with theoretical light curves requires precise knowledge of the distribution of…
The NewEra model grid
Peter H. Hauschildt, T. Barman, E. Baron +2
Analyses of stellar spectra, stellar populations, and transit light curves rely on grids of synthetic spectra and center-to-limb variations (limb darkening) from model stellar atmo…
Refractory and Volatile Species in the UV-to-IR Transmission Spectrum of Ultra-hot Jupiter WASP-178b with HST and JWST
Joshua D. Lothringer, Katherine A. Bennett, David K. Sing +17
The atmospheres of ultra-hot Jupiters are unique compared to other planets because of the presence of both refractory and volatile gaseous species, enabling a new lens to constrain…
Discovery and Detailed Study of the M31 Classical Nova AT 2023tkw: Evidence for Internal Shocks
Judhajeet Basu, Ravi Kumar, G. C. Anupama +11
We present a detailed analysis of an extragalactic slow classical nova in M31 exhibiting multiple peaks in its light curve. Spectroscopic and photometric observations were used to…
