The bright, well-known K5 giant Aldebaran, alpha Tau, is probably the star with the largest number of direct angular diameter determinations, achieved over a long time by several authors using various techniques. In spite of this wealth of data, or perhaps as a direct result of it, there is not a very good agreement on a single angular diameter value. This is particularly unsettling if one considers that Aldebaran is also used as a primary calibrator for some angular resolution methods, notably… 
Aldebaran's angular diameter: How well do we know it?

Aldebaran b’s Temperate Past Uncovered in Planet Search Data
The nearby red giant Aldebaran is known to host a gas giant planetary companion from decades of ground-based spectroscopic radial velocity measurements. Using Gaussian Process-based Continuous
Precise radial velocities of giant stars
Context. Using the Hamilton Échelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars over more than 12 yr, leading to the
Lunar Occultations with Aqueye+ and Iqueye
We report the first-time use of the Aqueye+ and Iqueye instruments to record lunar occultation events. High-time resolution recordings in different filters have been acquired for several occultations
The inner dust shell of Betelgeuse detected by polarimetric aperture-masking interferometry
Context. Theory surrounding the origin of the dust-laden winds from evolved stars remains mired in controversy. Characterizing the formation loci and the dust distribution within approximately the
High Time Resolution Astronomy Or High Speed Photometry
High Time Resolution Astronomy (HTRA) or High Speed Photometry offers opportunity to investigate phenomena that take place at timescales too fast for standard CCD imaging. Phenomena that occur within
