Madrid, Feb. 10 (Europa Press) –
A team of astrophysics, led by Yunnan’s observatories of the Chinese Academy of Sciences, has achieved significant advances in the study of the Metamorphic Super SN 2014C.
His work provides crucial information on the explosion mechanisms of this rare type of Supernova and the final evolutionary stages of its parents, according to the authors of the study, which is published in The Astrophysical Journal.
SN 2014C is a well -known supernova that has experienced a remarkable transformation in its spectral classificationevolving from an IB type initially poor in hydrogen to a hydrogen rich type.
This transformation suggests that the sn 2014c parents It had almost completely detached from its exterior hydrogen wrapping before the explosion, leaving behind a dense circuit material (CSM) in its vicinity. This rare and complex phenomenon has intrigued astronomers during the last decade.
Using 2.4 -meter Lijiang telescope observationsthe researchers published the most complete preliminary data on SN 2014c. These data provided early evidence of the interaction between the Supernova and the CSM, filling the void in the information about the internal layers of the CSM.
When building a model that incorporates radioactive disintegration and delayed interaction, the researchers successfully explained the complex and variable behavior of the SN 2014C light curve.
His observations revealed the detailed physical processes during the initial stages of the SN 2014C explosion and provided key clues for later spectral transformation. When integrating early photometric data, spectral data of late time and radio and infrared observations that cover a decade, the research team discovered that the CSM around SN 2014C is not uniformly distributed; Instead, it exhibits an U -shaped structure. This intricate circuit environment significantly influences the supernova light curve and spectral evolution.
