  We present the current status of and new results from our search for
exoplanets in a sample of solar-mass, evolved stars observed with the HARPS-N
and the 3.6-m Telescopio Nazionale Galileo (TNG), and the High Resolution
Spectrograph (HRS) and the 9.2-m Hobby Eberly Telescope (HET).
  The aim of this project is to detect and characterise planetary-mass
companions to solar-mass stars in a sample of 122 targets at various stages of
evolution from the main sequence (MS) to the red giant branch (RGB), mostly
sub-gaints and giants, selected from the Pennsylvania-Toru\'n Planet Search
(PTPS) sample, and use this sample to study relations between stellar
properties, such as metallicity, luminosity, and the planet occurrence rate.
  This work is based on precise radial velocity (RV) measurements. We have
observed the program stars for up to 11 years with the HET/HRS and the
TNG/HARPS-N.
  We present the analysis of RV measurements with the HET/HRS and the
TNG/HARPS-N of four solar-mass stars, HD 4760, HD 96992 , BD+02 3313, and TYC
0434-04538-1. We found that: HD 4760 hosts a companion with a minimum mass of
13.9 MJ (a=1.14 au, e=0.23); HD 96992 is a host to a msin i=1.14 MJ companion
on a a=1.24 au and e=0.41 orbit, and TYC 0434-04538-1 hosts an msin i=6.1MJ
companion on a a=0.66 au and e=0.08$ orbit. In the case of BD+02 3313 we found
a correlation between the measured RVs and one of the stellar activity
indicators, suggesting that the observed RV variations may originate in either
stellar activity or be caused by the presence of an unresolved companion. We
also discuss the current status of the project and a statistical analysis of
the RV variations in our sample of target stars.
