- MauranKilom 5y ago> pulses from pulsars are usually much shorter ...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....
- valyagolev 5y agoto continue our idle lazy speculation game “explain the title without really reading”, perhaps it’s just doppler effect…
- MauranKilom 5y agoDoppler effect would reduce both the emission interval as well as the radio frequency. Not to mention that an object (which is comparatively close to us, i.e. not just red-shifted due to distance) would have to move at very close to the speed of light to be red-shifted that much. Now that would be unlike anything we've seen before...
