Testing the 3-equation Kuhfuss Convection Model using the Sun
T. A. M. Braun, F. Ahlborn, F. Kupka +1
Simplified, one-dimensional models are necessary to model convection in the context of stellar evolution. By including the non-local effects of convection, turbulent convection mod…
Implications of a turbulent convection model for classical Cepheids
M. Deka, F. Ahlborn, T. A. M. Braun +1
The appearance of blue loops in the evolutionary tracks of intermediate-mass core He-burning stars is essential for explaining the observed characteristics of Cepheids. The blue lo…
New Methods of Identifying AGN in the Early Universe using Spectroscopy and Photometry in the JWST Era
Flor Arevalo Gonzalez, Titanilla Braun, James Trussler +7
We explore spectroscopic and photometric methods for identifying high-redshift galaxies containing an Active Galactic Nucleus (AGN) with JWST observations. After demonstrating the…
Testing a non-local 1-equation turbulent convection model: A solar model
T. A. M. Braun, F. Ahlborn, A. Weiss
Turbulent convection models treat stellar convection more physically than standard mixing-length theory by including non-local effects. We recently successfully applied the Kuhfuss…
Low-period spacing core-helium burning giants: `hot subdwarf analogues'?
S. Hekker, Y. Elsworth, T. A. M. Braun +1
Global stellar oscillations probe the internal structure of stars. In low- to intermediate-mass red giants, these oscillations provide signatures from both the outer regions of the…
Dynamical stellar masses of pre-main sequence stars in Lupus and Taurus obtained with ALMA surveys in comparison with stellar evolutionary models
Teresa A. M. Braun, Hsi-Wei Yen, Patrick M. Koch +3
We analysed archival molecular line data of pre-main sequence (PMS) stars in the Lupus and Taurus star-forming regions obtained with ALMA surveys with an integration time of a few…
