The star cluster system of the 3 Gyr old merger remnant NGC 1316: Clues from optical and near-infrared photometry

, 2001
The giant merger remnant galaxy NGC 1316 (Fornax A) is an ideal probe for studying the long-term effects of a past major merger on star cluster systems, given its spectroscopically derived merger age of ~3 Gyr which we reported in a recent paper. Here we

Hot Jupiters and Cool Stars

, 2014
Close-in planets are in jeopardy as their host stars evolve off the main sequence to the subgiant and red giant phases. In this paper, we explore the influences of the stellar mass (in the range 1.5--2\Mso ), mass-loss prescription, planet mass (from ...

Tank color affects growth, feed utilization efficiency, coloration, and biochemical composition of juvenile giant trevally (Caranx ignobilis Forsskål, 1775)

Fisheries and Aquatic Sciences
Tank color is an important environmental factor influencing aquaculture performance, but it remains poorly understood for juvenile giant trevally (Caranx ignobilis) under laboratory conditions.

The complete mitochondrial genome and phylogenetic analysis of red-and-white giant flying squirrel (Petaurista alborufus)

Mitochondrial DNA. Part B. Resources, 2020
Red-and-white giant flying squirrel (Petaurista alborufus) is a widely distributed but rarely studied species. Here, we sequenced the complete mitochondrial genome about it, which is a circular genome of 16,511 bp and have a typical structure with ...

Seismic diagnostics for transport of angular momentum in stars 2. Interpreting observed rotational splittings of slowly-rotating red giant stars

, 2012
Asteroseismology with the space-borne missions CoRoT and Kepler provides a powerful mean of testing the modeling of transport processes in stars. Rotational splittings are currently measured for a large number of red giant stars and can provide stringent

Asteroseismology of Very Low-Frequency Red Giants with Kepler: the Breakdown of the Asymptotic Relation

EPJ Web of Conferences, 2015
As the Kepler time series grew, so did the interest in the asteroseismology of very low-frequency solar-like oscillators. It is possible to accurately resolve modes for stars near the tip of the red giant branch.

Update on the APOKASC analysis of Red Giants

EPJ Web of Conferences, 2017
APOKASC is a collaboration between APOGEE's spectroscopic survey in the near IR at Apache Point (SDSS) and Kepler Asteroseismic Science Consortium (KASC) for the study of red-giant stars.

Circumstellar Na I and Ca II lines of type Ia supernovae in symbiotic scenario

, 2008
Formation of circumstellar lines of Na I and Ca II in type Ia supernovae is studied for the case, when supernova explodes in a binary system with a red giant.
