Neutron stars, the compact remains of a massive star following a
supernova explosion, are the densest matter in the Universe. Some
neutron stars, known as magnetars, also claim the record for the
strongest magnetic fields of any object. How magnetars, which are
a mere 15 kilometers across, form and produce such colossal
magnetic fields remains a mystery. 

 

New observations by a team of astronomers, including NSF’s
NOIRLab’s Dr. André-Nicolas Chené, may shed
important light on the origin of these magnetic powerhouses.
Using various telescopes around the globe, including the
Canada-France-Hawai‘i Telescope (CFHT) on Maunakea, the
researchers have identified a new type of astronomical object — a
massive magnetic helium star (an unusual variant of a Wolf-Rayet
star), which may be the precursor of a magnetar. 

In this podcast, André-Nicolas Chené describes the process of
finding the first known potential magnetar progenitor.

 

Bios: 

- Rob Sparks is in the Communications, Education and Engagement
group at NSF’s NOIRLab in Tucson, Arizona.

- Dr. André-Nicolas Chene is an associate astronomer at NOIRLab.
He completed his PhD at the Université de Montréal in 2007 and
learned everything about the fundamentals of astronomical
observations at the Observatoire du Mont Mégantic. He was
research fellow at the NRC Herzberg Astronomy and Astrophysics
Research Centre and postdoc jointly at the Universidad de
Concepción and the Universidad de Valparaíso before joining the
Gemini Observatory (now a program of NOIRLab) in 2013. For almost
10 years, André-Nicolas took part in every phase of a Gemini
observing program life cycle and has played a central role in
Gemini’s user support effort. André-Nicolas’s research interests
are massive stars, hot winds, star clusters, and stellar
evolution.

Mein Archiv

Deine Privatkopie der Folgen, die du nicht verlieren willst.

Podcast-Folgen verschwinden. Feeds werden auf die letzten Episoden gekürzt, Hoster räumen alte Dateien ab, Formate wechseln den Anbieter und lassen ihr Archiv zurück. Mit „Mein Archiv“ sichert podcast.de die Folgen deiner Podcasts für dich — angefangen bei den ältesten, denn die sind zuerst weg.

  • Deine gesicherten Folgen bleiben hörbar, auch wenn das Original offline geht.
  • Auch Folgen, die im heutigen Feed gar nicht mehr stehen — podcast.de kennt sie noch.
  • Herunterladen bleibt möglich, solange die Folge beim Podcaster liegt. Der zählt seine Abrufe wie bisher.
