DogsHeaven Observatory X87
Exploring the deep cosmos from the heart of Brazil. Led by discoverer Paulo Cacella, our facility specializes in transient phenomena, supernovae, and high-precision spectroscopy.
Scientific Discoveries & Research
Supernova SN 2002bo: Discovered by P. Cacella in NGC 3147, this Type Ia supernova became one of the most significant benchmarks for cosmological distance studies due to its early detection and extensive follow-up data.
XTE J0929-310: Our observatory contributed to the discovery and optical characterization of this accreting millisecond X-ray pulsar, providing vital data on the behavior of neutron stars in binary systems.
SN 2017dgk: A notable high-velocity supernova discovery that furthered our understanding of stellar explosions in distant galaxies.
Spectroscopy & Be Stars: DogsHeaven Observatory is a key participant in international spectroscopic campaigns (such as those involving the TESS satellite). Our work on spectroscopy focuses on mass ejection events and circumstellar disk formation in Be stars like λ Pavonis.
Tidal Disruption Events (TDE): In collaboration with global researchers, we monitor the rare and violent events where stars are torn apart by supermassive black holes, contributing to recent findings published in arXiv and major astronomical journals.
Our ongoing Survey work includes high-precision stellar occultations of Trans-Neptunian Objects (TNOs), helping to map the furthest reaches of our Solar System.
