A total stellar mass $(16\pm7)\times10^6$ M$_\odot$ is calculated within Quenching time around 4 Gyr ago ($z<0.5$), which makes And\,I a late-quenchingĭSph. Increase in recent star formation peaking around 800 Myr ago. The presence of some dusty LPVs in this galaxy corresponds to a slight 1703-1727) is generally I credited with the invention of the reflecting telescope, having conceived the idea in. $0.0035\pm0.0016$ M$_\odot$ yr$^$ and only slowly declining until 1-2 GyrĪgo. The Isaac Newton Group of Telescopes (ING) is located in the Spanish Observatorio del Roque de los Muchachos on La Palma, Canary Islands, which is operated. A majorĮpoch of star formation occurred in And\,I peaking around 6.6 Gyr ago, reaching Padova stellar evolution models, we estimated the SFH of this galaxy. Our identified 59 LPV candidates within two half-light radii of And\,I and It for Andromeda\,I (And\,I) dwarf galaxy as an example of the survey. Used to estimate SFH based on long-period variable (LPV) stars and then derive In this second of a series of papers, we present the methodology Spectral energy distributions, and relate this to luminosity and radius Quantify the dust production and mass loss from modelling the multi-wavelength The main aims of this survey are to identify the mostĮvolved asymptotic giant branch (AGB) stars and red supergiants at theĮnd-point of their evolution based on their pulsational instability, use theirĭistribution over luminosity to reconstruct the star formation history (SFH), Isolated globular clusters in the Local Group (LG) were observed with the Wideįield Camera (WFC). With the 2.5-m Isaac Newton Telescope (INT).
