...and more frequent.
- okokwhatever 5y agoThen it's a slow pulsar LOL Sorry, I had to make it :)
- delcaran 5y agoArticle says it's a theoretically possible object described as "slow magnetar".
- okokwhatever 5y agoDon't be so serious my friend, it was an easy joke, i know :)
- ianai 5y agoIs that really that mysterious? Just seems they went out of their way for clickbaity title.
- dekhn 5y agoThat's correct. The original paper doesn't call it mysterious, just "unusual". Science PR people are under a lot of stress to get pageviews.
- rbanffy 5y agoThe original description was most likely “hmmm… that’s funny”.
- Vetch 5y agoThe mysterious (unpredicted/as yet unexplained) aspect is the precise physics of its emission properties. It's a refinement of known physics sure, but that doesn't make it less interesting. Not unlike how finally completing a full physics accounting for how bicycles remain upright would be fascinating even if positively pedestrian.
- equalsione 5y agoPulsars usually "pulse" very rapidly and in very short bursts[0]. This one pulses only once every 18 minutes, but in bursts that seem to last for a minute. Some articles mention the possibility of a star-quake which as I _think_ could be caused by either further decay of the magnetar, or the magnetar absorbing more mass [0] - https://www.sciencedirect.com/topics/physics-and-astronomy/radio-pulsars#:~:text=At%20present%2C%20the%20shortest%20interval%20between%20successive%20pulses%20is%20about%201.5%C3%9710%E2%88%923%20%C2%A0s%20and%20the%20longest%20is%20about%205%C2%A0s https://www.sciencedirect.com/topics/physics-and-astronomy/r....
