Seminario de Astrofísica en el IFIS. El próximo martes 16 de junio a las 14:30 hrs, Constanza Castillo, estudiante de magíster en astrofísica (UC), presentará en el Instituto de Física el seminario:
“Formation of O-bearing Complex Organic Molecules in protoplanetary disks”.
La presentación se realizará en la Sala 208 del Instituto de Física (IFIS), 2° piso, Edificio de Ciencias, Campus Curauma, PUCV.
Revisa el abstract de la presentación:
Protoplanetary disks around young stars are the environment where planets form, making it crucial to characterize their composition and spatial distribution, as part of this material can be incorporated into forming planets. In this context, Complex Organic Molecules (COMs) are particularly interesting, as they are considered a bridge to prebiotic molecules and the initial steps of life’s formation. Among them, methanol (CH3OH), the simplest COM, is a key precursor to more complex species. However, its detection in disks remains challenging, as it is primarily locked in icy grains. Formaldehyde (H2CO), a brighter and more commonly detected molecule that shares formation pathways with methanol, can thus serve as a tracer of organic chemistry in disks. This work retrieves the excitation conditions and column densities of H2CO through disk-averaged and radially resolved analyses. By extending these studies beyond the small number of well-characterized disks currently available, we aim to compare the chemical properties of different planet-forming environments and constrain the origin of oxygen-bearing organic molecules in protoplanetary disks.
