International Group of researchers opened 18 events of the top destruction of stars (TDE) by super-minor black holes that are previously remained unnoticed by the dust in space. These phenomena, when the gravitational forces of the black hole break the star, occur about once every 10,000-100,000 years in each galaxy and are accompanied by a huge release of energy. However, due to dust, which hides radiation from optical to X-ray, the detection of such events was difficult.
Using infrared observations using NASA Wise (Wide-Field Infrand Survey Explorer) and Neowise, as well as other missions, researchers were able to detect these hidden events. Infrared waves are less susceptible to dispersion and absorption of dust, which allows you to see hidden phenomena in space.
Among the discovered events is the tidious destruction of the star, located in a particularly dusty star-forming galaxy, closest to the ground. This discovery sheds light on TDE demography in a local universe and allows you to explore the previously underestimated TDE class.
In addition, the detection of infrared signals from TDE helps to answer the question of “missing energy,” suggesting that many TDE simply were not found due to the absorption of their radiation with dust and gas. This discovery also assumes that TDE may not be such rare phenomena as previously thought, and future reviews, such as Legacy Survey of Space and Time (LSST) in the Out of Vera Rubin, can detect hundreds, if not thousands of such events annually.
This study not only expands our understanding of the tidal destruction of stars but also emphasizes the importance of infrared observations to study cosmic phenomena hidden behind dust.
