Avery Bailey, Andrew Youdin, Kaitlin Kratter Astro-ph: arXiv:2603.20373 In this paper, we extend the foundational work of Bondi (1952) to include the effects of radiative feedback in gas-pressure-dominated environments. We construct steady-state spherically symmetric...
Overlap of quiescent K and M dwarfs (red stars) with transiting exoplanet hosts (black dots) in stellar Teff and metallicity space. The range of targets selected for this proposal (blue circled red stars) allows for broad expansion and testing of model atmospheres in...
Due to the COVID19 panedemic, our AE team suspended most in-person interactions for more than a year; and the AE breakfasts for almost two years. In September 2022, we held our first real, in-person AE breakfast in a while. It has been great to meet team members again...
Protoplanetary disks offer an opportunity to learn about the processes by which planetary systems form and evolve. Images of these young systems also enable us to study, by analogy, the formation of our own Solar System, in which the common orbital plane of the...
The key goal of EOS is to advance our understanding of the formation of habitable planets. As an unusually large and ambitious program, EOS is in a rare position to successfully integrate interdisciplinary knowledge on planet formation – that is, to combine...
The Origins Seminar now has its own YouTube channel and the most recent talks are now available! Origins will continue to operate through most of the Summer and talks will be recorded and available through the Origins Seminar YouTube channel.
Research by University of Arizona Assistant Professor Pierre Haenecour and his team on the effect of ion irradiation on dust grains in circumstellar and interstellar environments, presented by Haenecour at Microscopy and MicroAnalysis 2019, has been...
The first unbiased survey of protoplanetary disks surrounding young stars in the Taurus star-forming region turned up a higher-than-expected number of disks with features suggesting nascent planets. Excerpt from UA News-Daniel Stolte, University Communications...
