Stars with a mass 1.5 times greater than the Sun are classified as intermediate-mass stars. They are more massive and hotter than our Sun, and they live shorter lives.

Here's a breakdown of their characteristics:

Mass: 1.5 - 8 solar masses

Lifetime: A few billion years (shorter than the Sun's 10 billion years)

Temperature: Hotter than the Sun, ranging from 5,500 to 10,000 Kelvin

Color: Yellow-white to white

Luminosity: More luminous than the Sun

Evolution:

* Burn hydrogen into helium in their cores.

* Expand into red giants as they exhaust their core hydrogen.

* Eventually, they become white dwarfs after shedding their outer layers.

Examples:

* Sirius A: The brightest star in our night sky.

* Procyon A: Another bright star visible in the northern hemisphere.

* Altair: A prominent star in the constellation Aquila.

Note: These are just a few examples. There are many other stars in our galaxy and beyond that fit this mass range.
