Both stars produce powerful gaseous outflows called stellar winds, which enshroud the stars and stymy efforts to directly measure their properties. Astronomers have established that the brighter, cooler primary star has about 90 times the mass of the sun and outshines it by 5 million times. While the properties of its smaller, hotter companion are more contested, Goddard's Ted Gull and his colleagues think the star has about 30 solar masses and emits a million times the sun's light.

During the past 11 years, spanning three close approaches or periastron passages, the Goddard group has developed a model based on routine observations of the stars using ground-based telescopes and multiple NASA satellites. According to this model, the interaction of the two stellar winds accounts for many of the periodic changes observed in the system. The winds from each star have markedly different properties: thick and slow for the primary, lean and fast for the hotter companion. The primary's wind blows at nearly 1 million mph (1.6 million km/h) and is especially dense, carrying away the equivalent mass of our sun every thousand years. By contrast, the companion's wind carries off about 100 times less material than the primary's, but it races outward as much as six times faster.

The 3-D time-dependent smoothed-particle hydrodynamics simulations, which were developed by Goddard theorist Thomas Madura, were performed on the Pleaides supercomputer at NASA's Ames Research Center in Moffett Field, California. The colors used relate either to density, temperature or wind speed differences, depending on the movie; see the captions for additional details.", "items": [], "extra_data": {} }, { "id": 344306, "url": "https://svs.gsfc.nasa.gov/11722/#media_group_344306", "widget": "Video player", "title": "", "caption": "", "description": "Density simulation.

Eta Carinae lies about 7,500 light-years away in the southern constellation of Carina and is one of the most massive binary systems astronomers can study in detail. The smaller star is about 30 times the mass of the sun and may be as much as a million times more luminous. The primary star contains about 90 solar masses and emits 5 million times the sun's energy output. Both stars are fated to end their lives in spectacular supernova explosions.Between 1838 and 1845, Eta Carinae underwent a period of unusual variability during which it briefly outshone Canopus, normally the second-brightest star. As a part of this event, which astronomers call the Great Eruption, a gaseous shell containing at least 10 and perhaps as much as 40 times the sun's mass was shot into space. This material forms a twin-lobed dust-filled cloud known as the Homunculus Nebula, which is now about a light-year long and continues to expand at more than 1.3 million mph (2.1 million km/h). Using the European Southern Observatory's Very Large Telescope and its X-Shooter spectrograph, the team imaged near-infrared, visible and ultraviolet wavelengths along 92 separate swaths across the nebula, making the most complete spectral map to date. The researchers have used the spatial and velocity information provided by this data to create the first high-resolution 3D model of the Homunculus Nebula.The shape model was developed using only a single emission line of near-infrared light emitted by molecular hydrogen gas. The characteristic 2.12-micron light shifts in wavelength slightly depending on the speed and direction of the expanding gas, allowing the team to probe even dust-obscured portions of the Homunculus that face away from Earth. || ", "release_date": "2014-07-08T10:00:00-04:00", "update_date": "2023-05-03T13:50:45.782762-04:00", "main_image": { "id": 454554, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011500/a011568/EtaCarinae_STILL.png", "filename": "EtaCarinae_STILL.png", "media_type": "Image", "alt_text": "This animation sequence zooms into a Hubble image of the Homunculus Nebula, then dissolves to the shape model, which rotates to provide views from various angles.
