Indian Defense Minister Abruptly Calls off Visit to UK Over ‘Scheduling Issues’_我的网站

一 |     在他们的观测中，天文学家注意到，这个“棉花糖”世界，正如许多人所认为的那样，似乎比我们之前探测到的任何其他气态巨行星的密度都要低得多。此外，它与它所环绕的红矮星的距离很近，这引起了关于该行星形成的更多问题。    India’s Defense Minister Rajnath Singh has postponed his three-day trip to the UK, days after a high-level delegation of British Sikh soldiers visited religious, cultural, and historical sites in Pakistan.,The visit was not formally announced by the two sides, but the government sources in Delhi revealed that Singh, who had planned to lead a high-level defense team including industry leaders, was scheduled to begin his three-day visit to the UK on Sunday.,“Scheduling issues are the reason. Something comes up at the last moment, and dates need to be revised,” an Indian government official told Sputnik on condition of anonymity.,However, the Defense Ministry spokesperson offered “no comment” when asked if the development is linked to a recent visit to historical and religious places in Pakistan by 12 British Sikh soldiers.,The media wing of the Pakistan Armed Forces said that the British delegation, headed by a major general, met with General Qamar Javed Bajwa on 28 June at the Army headquarters, also visiting several religious places linked to Sikh pride.,New Delhi accused Islamabad and Pakistan's Army of fueling Sikh resentment in India's Punjab by extending support to the secessionist movement demanding a separate Sikh homeland named Khalistan.,Two days prior to Singh's visit, British Prime Minister Johnson also accused Indian authorities of "arbitrarily" detaining British-Sikh national Jagtar Singh Johal, who was charged by India's National Investigative Agency (NIA) with being a member of the banned Khalistan Liberation Front (KLF).,"I don't think there's any reason for India to be so irked as to postpone the defense minister's visit to the UK with which we've been negotiating a Free Trade Agreement. In fact, any such linkage will be counterproductive," Amit Cowshish, former financial advisor to the Indian Defense Ministry, told Sputnik.,Ahead of Singh's proposed visit to the UK, Minister for Defense Procurement Jeremy Quin told The Economic Times, an Indian daily, about possible collaboration on maritime electric propulsion systems, fighter aircraft, and jet engine technology between the two countries.,During his visit in April, Johnson offered defense tech know-how to India to give an impetus to the modest UK-India defense ties.,Want to know more?

二 | 据信，气态巨行星开始时是巨大的岩石核心，质量是地球的10倍。从那里，它们迅速拉入大量邻近的气体，形成我们今天所知道的“巨无霸”。其他的气态巨行星，如木星，甚至可能因吞噬其他行星而长到如此大。这颗被称为TOI-3757 b的行星有可能在其核心内有较低的重元素丰度，因此岩质核心形成得更慢，推迟了气体吸积的开始。未来对这个“棉花糖”世界的观察（也许用詹姆斯-韦伯太空望远镜）可以告诉我们更多关于它的大气和密度的信息。

三 | 研究人员在《天文学杂志》上发表了一篇关于该行星的论文。
