Theoretical red-giant branches for globular clusters [PDF]
Symposium - International Astronomical Union, 1984 VandenBerg (1983a; hereinafter V) has recently computed a large grid of stellar evolutionary sequences from the zero-age main sequence to the base of the red-giant branch (RGB) and carried out extensive comparisons of the associated isochrones with published photometry of globular clusters (GCs).

The analysis of red giant branch photometry in galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We present an analysis of the many possible methods for simulating and analysing colour-magnitude diagrams, with application to studies of the field halo stellar populations of resolved galaxies. Special consideration is made to the analysis of stars on the Red Giant branch (RGB), and methods for obtaining metallicity distributions for old populations ...

Detection of the Tip of the Red Giant Branch in NGC 5128 [PDF]
The Astrophysical Journal, 1996 We present a color-magnitude diagram of more than 10,000 stars in the halo of the galaxy NGC 5128 (Centaurus A), based on WFPC2 images through V-band and I-band filters. The position of the red giant branch (RGB) stars is compared with the loci of the red giant branch in six well-studied globular clusters and in the dwarf elliptical galaxy NGC 185; the

A Red Giants’ Toy Story. II. Understanding the Red-giant Branch Bump
The Astrophysical Journal, 2023 The Red-Giant Branch Bump (RGBB) is one of the most noteworthy features in the red-giant luminosity function of stellar clusters. It is caused by the passage of the hydrogen-burning shell through the composition discontinuity left at the point of the ...

Quantifying Uncertainties on the Tip of the Red Giant Branch Method
The Astronomical Journal, 2023 We present an extensive grid of numerical simulations quantifying the uncertainties in measurements of the tip of the red giant branch (TRGB). These simulations incorporate a luminosity function composed of 2 mag of red giant branch (RGB) stars leading ...

Hubble Space TelescopeObservations of the Large Magellanic Cloud Field around SN 1987A: Distance Determination with Red Clump and Tip of the Red Giant Branch Stars [PDF]
, 2000 We have used HST-WFPC2 multiband observations of a field around SN 1987A in the Large Magellanic Cloud to measure its distance from the Sun. The observations allowed us to carefully determine the interstellar extinction along the line of sight to a large

The Metallicity of the Red Giant Branch in the Disk of NGC 6822 [PDF]
Publications of the Astronomical Society of the Pacific, 2003 Deep J, H, and K' images obtained with the Canada-France-Hawaii Telescope adaptive optics system are used to investigate the metallicity of red giant branch (RGB) stars in three fields in the disk of the Local Group dwarf irregular galaxy NGC 6822. The slope of the RGB on the (K, J-K) color-magnitude diagrams indicates that = -1.0 +/- 0.3. The locus of

Red variables in the OGLE-II data base - I. Pulsations and period-luminosity relations below the tip of the red giant branch of the Large Magellanic Cloud [PDF]
, 2003 We present period-luminosity relations for more than 23,000 red giants in the Large Magellanic Cloud observed by the OGLE-II microlensing project. The OGLE period values were combined with the 2MASS single-epoch JHK photometric data.
