  • Why did you choose astrophysics?

    How the universe is created is the biggest unanswered question in the astrophysics.Here is the solution for this unanswered question.As per law of conservation of energy, energy can neither be created nor destroyed. Your universe is made up of mass and energy. This means universe does not exists. But universe exists..

CORE Accretion vs. Disk Instability

There are two main ways we think planets form in these protoplanetary disks. The core accretion mechanism holds that a gas-giant first forms a large, mostly rocky, core with enough mass and hence gravity to pull in gas from the surrounding disk to form a thick atmosphere, eventually becoming huge gas worlds. The competing idea is the disk instabili.

Do Metal-Rich Stars Make Metal-Rich Planets?

The relationship between the compositions of gas giants and their host stars is key to understanding planet formation. We know that close-in (hot) giant planets are more often found around stars with high iron abundances/metal abundances in general. This led to the obvious question: Do metal-rich stars also make metal-rich planets? Teske and her co.

How do astronomers detect a planet's presence?

Similar to radial velocity, astronomers using the astrometry method detect a planet's presence indirectly through the wobble of the host star around the center of mass of the system

However, instead of measuring the changes in velocity, astrometry relies on precise measurements of the star’s position

How do scientists find exoplanets?

There are two main ways scientists at Carnegie find exoplanets

In the transit method, a planet passes between a star and our telescope so astronomers measure a dip in the light

How Do Sub-Neptunes and Super-Earths form?

These planets are the most common in the Galaxy, and yet we don't have one in our Solar System. To understand why we first need to know what these planets are made of so we can attempt to pin down how they are formed. To do this, astronomer Johanna Teske takes mass and radius measurements of planets to estimate their compositions. She is also start.

Modelling System Development

It takes up to hundreds of millions of years for a planetary system to form. Constructing mathematical models of Solar System creation is another way scientists fill in the gaps and test out new theories. Theoretical astrophysicist Alan Bosscreates mathematical models of disks using the information we know from observations like those done by Weinb.

Observing Disks and Planet Development

Observational astrophysicist Alycia Weinbergerdirectly observes protoplanetary disks in order to understand how planets form. Weinberger uses a variety of observational techniques and facilities to tease apart disk development. For example, with the Hubble Space Telescope,Weinberger images the smallest dust grains in disks at different wavelengths .

What is the Center for Astrophysics & Smithsonian doing?

The research at the Center for Astrophysics | Harvard & Smithsonian centers on humanity’s greatest unresolved questions about the nature of the universe

These questions have been pondered for generations, and our research is bringing us closer to answers than ever before

Does life exist outside of the solar system?

What is the future of Astrophysics?

"The coming decade will be an extremely exciting time for astrophysics with the next generation space- and ground-based telescopes being built and coming on-line

The CfA's strength is the expertise of its scientists and researchers across the full electromagnetic spectrum from the X-rays through to the radio and sub-mm
