Save the Date! Planning is in progress for a conference to be held in Ensenada, Baja California, México on:
11th – 14th December 2023
Contact: This email address is being protected from spambots. You need JavaScript enabled to view it.
The theme of this conference is to celebrate the lifetime work of You-Hua Chu and her contributions to astronomy. The first four days (11th – 14th December) are planned for talks and discussion, while the fifth day (15th-16th December) is planned for an excursion out to the TAOS2 site. Though due to TAOS2' accommodation constraint, it is limited to a small group.(subject to weather conditions and availability of accommodation at the observatory)
You-Hua’s scientific interests have spanned a broad range of topics in studying the contributions of stellar feedback in various forms to the interstellar medium. Her work with her colleagues, students, and collaborators over the years has spanned the range from studies of young massive stars and their clusters, HII regions and stellar-wind bubbles, to the end of star life in planetary nebulae and supernova remnants, larger interstellar structures, and other drivers of stellar feedback in the Milky Way, the Magellanic Clouds, and galaxies beyond. The goal of this meeting is to bring together collaborators and researchers to present the most recent developments in all of these areas, discuss key questions in the current field, and encourage discussion and collaboration on these questions and possible approaches to address (maximum 100 people in person).
This conference will include invited and contributed talks, and poster presentations. A hybrid format will allow participants to choose to attend in-person or remotely on a virtual platform. Talk slots will be preferentially given to those attend in person since this is an event to celebrate with You-Hua Chu. We note that registration for in-person attendance will be limited to 100 participants and once the capacity of the conference venue is reached, any additional in-person registrants will be placed on a waiting list.
Topics planned to be covered at this meeting include:
Young Stars, Star Clusters, and HII Regions
You-Hua has studied the large star-formation region 30 Doradus in the Large Magellanic Cloud, as well as similar regions, and other drivers of feedback in HII regions. We will expand this topic to finding young stars and defining their properties; links between massive star formation and its molecular environment; the collective input from young star clusters; and dust-gas dynamics in circumstellar disks.
Massive Stellar-Wind Bubbles
You-Hua’s work has studied of massive stars such as luminous blue variables and Wolf-Rayet stars, and we will discuss the impact of these bubbles singularly and collectively. In particular, we will discuss both the hot and cool gas in nebulae.
Stellar Clusters and Superbubbles – Feedback to the ISM
Much of the modeling of stellar feedback into the interstellar medium includes observations of existing superbubbles. We will discuss current observations of such superbubbles; models of superbubble formation and shaping of the regional interstellar medium; and their large-scale input into galactic outflows and winds in high-mass galaxies.
Planetary Nebulae
We will examine planetary nebulae at all wavelengths. In particular, we will examine the hot interiors of planetary nebulae as seen in X-rays.
Supernova Progenitors and Supernova Remnants
You-Hua and her collaborators have greatly extended the study of supernova remnants and their progenitors in the Magellanic Clouds, and we will review the new in that field. We will also discuss the implications of Type Ia Supernova Remnants being shaped by their binary progenitors.
