A luminous red nova (abbr. LRN, pl. luminous red novae, pl.abbr. LRNe) is a stellar explosion thought to be caused by the merging of two stars. They are characterised by a distinct red colour, and a light curve that fades slowly with resurgent brightness in the infrared. Luminous red novae are not related to standard novae, which are explosions ...
This and other luminous red nova events are thought to be caused by the merger of two stars. In the case of V838 Monocerotis, it was the merger of two main sequence stars, or an 8 M ☉ main sequence star and a 0.3 M ☉ pre-main sequence star. The merger model explains the multiple peaks in the light curve observed during the outburst. [14]
Artist's conception of a white dwarf, right, accreting hydrogen from the Roche lobe of its larger companion star A nova (pl. novae or novas) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star (hence the name "nova", Latin for "new") that slowly fades over weeks or months.
Luminous red nova, an explosion thought to be caused by stellar collision Solar flares are a minor type of stellar explosion [ 1 ] Tidal disruption event , the pulling apart of a star by tidal forces
Nova T Pyxidis – remnant. Most novae require a close binary system, with a white dwarf and a main sequence, sub-giant, or red giant star, or the merging of two red dwarfs, so probably all nova remnants must be associated with binaries. [4]
The agency issued a red flag warning — indicating an increased risk for fire danger — to 19 million people. Wind gusts topping 70 mph were recorded at several locations across the region.
The light curve continues to decline in the B band while it may show a small shoulder in the visual at about 40 days, but this is only a hint of a secondary maximum that occurs in the infra-red as certain ionised heavy elements recombine to produce infra-red radiation and the ejecta become transparent to it. The visual light curve continues to ...
Authorities have identified the woman who burned to death after she was set on fire inside a New York City subway train as 57-year-old Debrina Kawam. At a news conference, New York City Mayor Eric ...
