Giant stars die a violent death. After a life of several million years, they collapse into themselves and then explode in what is known as a supernova.How these stars explode remains a mystery. Howeve...
Stellar Evolution Constraints on the Triple-Alpha Reaction Rate
Stellar Evolution Constraints Triple-Alpha Reaction Rate
2011/10/19
We investigate the quantitative constraint on the triple-alpha reaction rate based on stellar evolution theory, motivated by the recent significant revision of the rate proposed by nuclear physics cal...
A giant planet in the triple system HD132563
individual: HD 132563 - Planetary systems - (Stars:) binaries: visual - (Stars:) binaries: spectroscopic - Techniques: spectroscopic
2011/9/28
As part of our radial velocity planet-search survey performed with SARG at TNG, we monitored the components of HD 132563 for ten years. It is a binary system formed by two rather similar solar type st...
Transit timing variations in eccentric hierarchical triple exoplanetary systems. I. Perturbations on the time-scale of the orbital period of the perturber
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We study the long-term time-scale (i.e. period comaprable to the orbital period of the outer perturber object) transit timing variations in transiting exoplanetary systems which contain a further, mor...
Close Separation Triple System QSO 1009–0252 with Discordant Redshifts:
Quasars emission lines absorption lines—individual
2010/9/15
1009-0252 is a Quasi Stellar Object (QSO) with three components A, B, C. A, B are thought to be the result of gravitational lensing of one object, and A, C constitute a close pair with redshifts 2.74 ...
