TITLE:

ON THE RELATIONSHIPS BETWEEN HABITABLE ZONE AND CIRCUNSTELLAR DEBRIS DISC WITH SPITZER PHOTOMETRY

KEY WORDS:

Debris Disk, Habitable Zone, Spitzer

PAGES: 28
BIG AREA: Ciências Exatas e da Terra
AREA: Física
SUMMARY:

A series of studies have been dedicated to investigating the correlation between the presence of debris disks around stars and their intrinsic characteristics, such as metallicity, rotation, and age. However, in the scientific literature, there is still a gap regarding the understanding of the relationship between the existence of debris disks and the circumstellar habitable zone, as well as the potential impact of the extent of the habitable zone on the behavior of circumstellar material. The present research project, to be conducted within a postgraduate program, aims to comprehensively analyze the impact of the circumstellar habitable zone on the material present in debris disks. The adopted methodology will involve reevaluating the stars previously investigated in my dissertation, this time using photometric data obtained through the Spitzer telescope. Additionally, we will employ the model developed by Kopparapu to accurately calculate the habitable zones around these stars.
